Copenhagen airport closure due to reported drone activity

Just the same old story, someone saw something, police officers also saw something, the airport is closed until someone that knows what they are doing can check from the sky, no pictures or videos of the drones in question.

In fairness to those in charge of airport operations, they probably don't have much choice but to stop flights if drones (or any other potential hazards) are reported, even if they're aware that nothing has been found in the case of similar drone reports elsewhere.

They don't want to be at a news conference or enquiry after a real near-miss or worse, where someone asks
"...but you were advised of sightings of drones earlier that day, weren't you?"

Stopping flights obviously inconveniences thousands of people, and can have wider economic consequences. Civil aviation is big business; maybe the relevant interests will be able to cooperate and fund/ implement effective monitoring and safe practices/ countermeasures that might limit disruption caused by drone reports in the future.

Compares favorably with having to respond to "report of man with gun" (rarely pans out) and "bomb threat" (usually threat, rarely a bomb).
 
Exiting news from the journalist I talked to, who haven't given up on the case.
https://www.zetland.dk/historie/smpQb9cQ-aOPVxA4K-9dd92

"It turns out that the air traffic controllers — the ones who oversee Copenhagen Airport and have the authority to shut down the airspace over the capital — didn't actually see any drones that day, despite having the best possible view of the airport.

This is revealed in a previously unpublished report from Naviair, the state-owned company responsible for managing Danish airspace.

The document is an internal incident report written at Naviair around lunchtime the day after the shutdown. It details what the staff experienced that evening and night. According to the report, even though it would normally be possible to "see the drone out the window," as it says, the controllers observed nothing.

Instead, Naviair reports that around 8:30 p.m., they only heard about the drones from the main command center at Copenhagen Airport — the so-called Operations Center (OC). There, they were told about two drones. Later, Naviair heard talk of "up to four drones."

So we now know that the alarm was raised solely based on what someone claimed to have seen and reported to the OC. And that those who normally monitor the airspace over Copenhagen Airport throughout the evening and night never saw a single drone."


And:

"The Naviair report also provides at least one other interesting detail. For the first time, it specifies where in the airport the drones were supposedly seen. According to the report, the very first message from the control center stated that "two drones were observed over Terminal C." It had previously been reported that the drones were flying "in different directions."


Terminal C is a long row of gates stretching out toward the runway. On that specific evening, the training plane passed very close to Terminal C twice within a few minutes, first heading east and then west. According to our analysis of the flight data here at Zetland, the second pass took the aircraft to within just 180 meters of Terminal C, flying at an altitude of around 130 meters."
 
"It turns out that the air traffic controllers — the ones who oversee Copenhagen Airport and have the authority to shut down the airspace over the capital — didn't actually see any drones that day, despite having the best possible view of the airport.
And this is the incident that kicked off the whole European flap.

All the people saying "ATC saw the drone... they wouldn't shut down the airport for a plane" were wrong, it seems.

This is an informative article. These journalists have done a good job. I recommend going to their site (non-paywalled) to give them traffic and to read in full, but here are a few more snippets (google translated) below.

It turns out that the air traffic controllers – those who keep an eye on Copenhagen Airport and can decide to close the airspace over the capital – didn't see any drones that day, despite the fact that they have the absolute best view of the airport.

This is shown in a previously unpublished memo from Naviair, the state-owned company that looks after the airspace over Denmark.

The note is a so-called sequence of events written at Naviair at lunchtime the day after the shutdown. It details what the staff at Naviair experienced that evening and night. And it states that although it would normally be possible to " Look at the drone out the window," as it says, the air traffic controllers observed nothing.

Instead, Naviair says that at around 8:30 p.m. they only heard about the drones from the large command center at Copenhagen Airport – the so-called operations center or OC . There were allegedly two drones here. Later, Naviair heard about " up to four drones".

So we now know that the alarm was raised solely on the basis of what someone saw and reported to OC . And that those who normally monitor the airspace over Copenhagen Airport during the evening and night never saw a single drone.
[...]
In any case, Danish police have informed Swedish police that someone at the airport initially thought they had seen a small plane flying close to the airport, but then changed their mind and believed that what they saw in the evening sky must be a larger drone.

The theory is that – in roughly the same minutes – there was both a training plane that could be mistaken for a drone, and actually a drone that flew over Northern Europe's largest airport at a low altitude and at an unusual time.
[...]
But we know that the closure of Copenhagen Airport was the beginning of a long series of temporary closures and drone sightings, and then we know that the authorities – after 50 days – have not yet presented a single piece of evidence of any kind.

In this regard, I still think a lot about what Mette Frederiksen subsequently said in an interview with TV 2:

"If we make it a goal in itself that there must be concrete evidence, then I think we are focusing in the wrong place."
[...]

This last part is a little startling. I had not seen this interview they refer to. This is the Prime Minister of Denmark essentially telling a news outlet to stop asking for evidence for the large, untraceable drones which allegedly flew for hours over a major international airport, and then multiple other airports and military facilities, over multiple weeks, undetected by ATC, undetected by military surveillance, not evidenced by any airport surveillance footage or any footage of any kind, and which were the basis for the Prime Minister giving a speech about the nation of Denmark being under attack. Here is the article+interview link, and an excerpt, in which TV2 also says they talked to people who have been in the classified briefings on the topic and those that answered said explicitly that they have yet to see any evidence.

To me, it seems unacceptable that officials have allowed the narrative of a drone attack on a major civilian airport to stand, if they do not have evidence for it. It is unacceptable for airport officials to claim to have surveillance recordings providing evidence for it, but still, nearly two months later, for them to refuse to provide it or even describe what it shows. This is a civilian airport and there is no security justification for not releasing this information, and given the stories it has generated there is actually a strong security justification in favor of releasing it. The fact that the Prime Minister has brushed aside a need for evidence, and other officials who've been in classified briefings on the subject told reporters that they've not been provided any evidence, suggests that there actually isn't any.

On Tuesday at the opening of the Folketing, the Prime Minister refused to answer whether she had personally seen "concrete evidence" that it was drones that had closed the airspace over several Danish airports and military facilities since September.

- What is important is that we see the pattern in Europe instead of looking at the specific events, Mette Frederiksen replied on Tuesday.

But have you seen concrete evidence?

- If we make it a goal in itself that there must be concrete evidence, then we are focusing in the wrong place, she said.

While the majority of politicians refused to comment on the secret briefings about activity in Danish airspace, several tell TV 2 that they have never seen evidence that drones were involved.


We haven't seen any evidence, say several parties
Since the closure of Copenhagen Airport's airspace, the party leaders of the Folketing have been regularly invited to confidential briefings on the situation.

Orientations where no evidence has been presented.

- I have not seen anything in writing about what it is that has been hovering over Danish soil, says the leader of the Conservative Party, Mona Juul.

Neither have the Liberal Alliance seen any tangible evidence of the drones.

- No, I haven't. But I assume it's drones, otherwise it's too strange that they've held one press conference after another, says party leader Alex Vanopslagh.

None of the nine party leaders that TV 2 has asked will say that they have seen evidence that the drones have flown over Denmark.

Yes even the airport said they had proof and videos.

It's useful to go back to the timeline and sources here because this is also a good point and it would be very nice to know what they were talking about when they referred to surveillance data proving the presence of multiple drones. The 'Operations Director' at Copenhagen/Kastrup airport was interviewed by TV2 and was quoted as saying it in another article they published on 2025-10-07.

Here: https://nyheder.tv2.dk/krimi/2025-1...-til-lukning-af-luftrum-nu-afviser-lufthavnen
(If you are google-translating this article or other articles in Danish, keep in mind that 'fly' should translate to 'airplane', but sometimes these systems translate it to 'aircraft', even mixing different translations within the same article.)

External Quote:
But the airport's operations director, Kristoffer Plenge-Brandt, now rejects these speculations in an interview with TV 2.

"Our employees can definitely determine whether it was a plane or not. We know it wasn't," says the operations director.

He explains that the closure of the airport on the evening itself was based solely on observations from employees, but that the airport has since retrieved data from surveillance systems, which, according to the director, documents that there were drones over Copenhagen Airport.

The director does not want to disclose what the data specifically shows.
So they said this specifically to push back on the TV2 reporter raising the question of whether the small training airplane could have been visually misidentified, as well as asserting that their employees cannot be mistaken. This leads me to think the employee who initiated the sighting was an employee of the airport Operations Center.

It is unclear if this employee filmed one or both of the videos which an airport employee then given to TV2 when they arrived. Particularly the video believed to be first chronologically, of the more distant craft, flying to the right, viewed over one of the terminal buildings. Them not being involved in that recording raises the "why were they filming?" question. It is possible that the first employee very quickly sent out a radio notice to other employees to look at the sky and look for drones, and this video was recorded by a different employee who very quickly began filming and got the small plane on video. But if I had to bet, I'd probably put slightly higher chances on the first video being recorded by the employee who initiated the sighting.

Also to re-emphasize a key point from this older TV2 article, the videos that TV2 published were given to them by an airport employee when TV2 arrived at the airport the next morning to cover the incident. TV2, upon further investigation after having published those videos, now believes that what they were told by that airport employee was incorrect, and that the videos actually show the small training plane. So TV2 is saying that at least one airport employee believed that these videos of the small plane showed a large illegal drone. At minimum, the employee who gave them the videos. It would be useful to know who gave them the videos. Someone in the Operations Center? This article is also critical of their own past reporting, which is greatly appreciated and should be highly valued from a journalistic outlet.

@ThomasH do you think you could convince these journalists to publish the entire Naviair document they obtained? Maybe with redactions of personally identifying details if necessary? But if they obtained it via official channels then they should be allowed to publish what they were given with no further redactions needed.

I can ask him.

And thanks for your long post before :)
There have also been a rumour that none of the police officers saw anything for the 4 hours they where there.

Out prime minister uses fear all the time, to show she's the one who keeps us all safe, it's sickening!
The minister of justice seriously said: "Just as the threat of terrorism became part of our reality after September 11, hybrid attacks have become part of our new reality."

That's getting rather political :)
Many Europeans believe there is a state-sponsored risk to their collective security and wellbeing, and the evidence for this is very, very strong.
But there's no good evidence that drone sightings at Copenhagen Airport are a part of this, and @ThomasH's (and others) substantial work must seriously call into question if there were any drones (of whatever origin) present at all.

I don't believe the politicians faked it, but I believe they talked it up and used the occasion to push their agenda.

With the possibility that they were also fooled and reacted as if it were all real because they believed (and possibly continue to believe) that the sightings were real.
 
Authorities rarely own up to mistakes, also they can seek opportunities to capitalise and misuse incidents. Gatwick was misused by the UK Home Office, police, DfT and arguably the CAA. The incident was used as an argument for RID (including funding) and to push through some reshaping of the laws.

I've had to go to Tribunal (court) 4 times already and have 2 more cases already next year mainly due to Gatwick. Albeit Lakenheath is likely to result in at least 1 case. I've uncovered evidence being deleted and have uncovered being lied to about information that was held as well.

I have mentioned this to journalists in Denmark and Belgium and encouraged them to use Freedom of Information if their laws allow sooner rather than later

I have never heard of any country staging an incident but I have heard of a counter drone company allegedly asking a drone pilot to fly at a location to get some negative headlines...
 
@Kyle Ferriter @ThomasH I'm the journalist, and I just uploaded the Naviair-document to the story. You can find it here: Alle kiggede efter droner i Københavns Lufthavn. Men nyt notat afslører, at kontroltårnet ikke så nogen.
Dear *****,


Here is a brief summary of yesterday's incident from Naviair's perspective.

Short summary of the events:

Naviair was notified by Copenhagen Airport's Operations Center yesterday evening, 22 September, at 20:30.
The report stated that two drones had been observed above Terminal C.
Immediately afterward, Naviair initiated a controlled shutdown of traffic to and from Copenhagen Airport in accordance with operational procedures (see below).
Later, it was reported that up to four drones had been seen.

At 21:26 local time, SAS1688, an ATR, landed on runway 22L at "pilot's discretion" after issuing a MAYDAY call related to low fuel.
After coordination with CPH, traffic operations resumed at 00:25.

Points of attention:
Naviair does not have equipment capable of detecting drones and is therefore dependent on notifications from Copenhagen Airport through visual contact or information from drone radars. Alternatively, air traffic controllers in the control tower might potentially be able to see the drone out of the window.

Workload among our staff was at times high due to the short notice and somewhat unfamiliar tasks. In addition, extra night and morning shifts were called in to handle the atypical traffic scenario related to recovery and re-establishment of service.

---

I don't read that line, like it is 100% confirmed they didn't see anything, do you?

First post by regional police at 2025-11-16 22:06Z (23:06 local). The followups were posted this morning after I'd already narrowed down the closing time to around 9:15-9:20p local time but they confirm what I had guessed. This case involves ATC making the initial report. It sounds like a visual sighting. And no drones were found.

Cases like this are a little confusing because large drones would show up on radar, and in cases where large drones have been confirmed near borders with Ukraine and Russia, they were indeed immediately detected and tracked on surveillance platforms. But in these cases it's never flagged on sensors, it's only visual sightings. So it's either very small drones, or not drones.

For Aalborg arrivals, there was 1 cancelled, 3 delayed. Unclear if the cancellation was related. 1 delay definitely was, and the others likely were. 1 diversion and 1 delay listed on the FR24 arrivals board were the same flight. The plane temporarily landed in Billund but then after Aalborg reopened it continued to there. So the arrivals board shows 1 cancel, 1 divert, 3 delay.

Last landing prior was JP486 landing at 20:13Z.

The next due in was SK1221 (plane: SE-RON) from CPH, which was scheduled to depart Copenhagen at 20:20Z, but was cancelled. It has only arrived and parked from its prior flight at 20:08 so it was unlikely to make that 12 minute turnaround anyways. I'm not sure why it was cancelled. Maybe due to the anticipated delay they were able to consolidate passengers onto SK1225 or

D83098 was scheduled to leave Copenhagen at 20:30Z but delayed until 22:45Z. The plane was SE-RPS (serial 41143) and it has already been parked there for over an hour and a half. CPH was not closed during this period. So perhaps this delay was due to a disruption at Aalborg. Copenhagen->Aalborg is only a 30 minute flight so if there was a reason they couldn't land in Aalborg maybe there'd be no point taking off, as that would require taking enough fuel to possibly hang out in a holding pattern nearby for who knows how long, and maybe even end with returning to Copenhagen.

KL1289 (callsign: KLM91K, plane: D-AGMP) was scheduled to land at 21:30Z but was diverted to Billund. It left Amsterdam at 20:28Z but that is a longer flight and perhaps they were optimistic that Aalborg would be back open by the time they got there. It entered a holding pattern outside Aalborg at 21:23Z, and was finally diverted to Billund at 21:35Z. These short flights probably do not bring a lot of extra fuel and can't hang out indefinitely in holding patterns. If they do get diverted they need enough fuel to make it to where they were diverted to. After hanging out on the ground in Billund, it then departed Billund to complete it original flight to Aalborg on callsign KLM91K again (but no flight number). D-AGMP did not depart Billund again until 23:58Z though Aalborg had been open prior to that.

SK1225 (plane: SE-ROC) was scheduled to leave Copenhagen at 22:05 but was delayed until 23:09Z, leaving 16 minutes after D83098.

I'd guess Aalborg closed between 20:13Z and 20:20Z (or 20:30Z if the cancellation was unrelated), in time to notify the next flights from Copenhagen to Aalborg to not leave yet. KL1289 was a longer flight from Amsterdam so still departed at 21:30Z but made a temporary landing/refueling in Billund because Aalborg was still closed. No departures from Aalborg were affected because there weren't any scheduled.

I wonder if this strange approach to the airport has anything to do with it?
This time it looks like it's the flight controllers reporting though, so I guess that's unlikely.

I don't read that line, like it is 100% confirmed they didn't see anything, do you?
I don't read Danish but my understanding is that it is saying Naviair doesn't have have drone-detecting equipment, so relies on information from the airport itself, or on staff looking out of the windows of the control tower. (Presumably staff in the control tower are with Naviair rather than the airport itself?)
My reading is that ATC (Naviair) did not see any drones, and only received information about drones from the airport operations center (CPH employees).

I'm not saying this is related, but since the airport and police have refused to provide more details, people (including Danish politicians!) are left to speculate. The memo says two drones were reportedly seen, then later this became "up to 4 drones". So two, then later maybe another two. I will just note here the coincidence between this, and the videos that have been made public from that evening. Two videos were recorded by 1 or 2 airport employees just prior to ATC being notified of drones, and these videos were provided to TV2 by an airport employee, described as showing the drones flying over the airport. About two hours later, an additional two videos were recorded out the window of a Norwegian airlines plane and sent to Norwegian news outlet NRK for immediate publishing. So if you thought these videos showed drones... that's two... then later maybe another two.

The memo also indicates that CPH ATC does not have systems which are good at detecting/tracking small drones, so relies on other detection methods or on information from the airport operations center. ATC will have traditional radar systems used by airports, both long range radar for tracking flights in the large region around the airport, and short range surface-movement-radar for creating a 2D map of things within the airport. Neither are good at tracking very small drones.

It's a bit fuzzy what drone-tailored surveillance CPH, or specifically CPH ATC, had as of 22 September. It does mention "drone radar" but not clear what this means, or whether it literally means radar, or just a situational awareness map created by an RF surveillance system (like DJI Aeroscope). Or whether it is ATC which has this, or whether it is the operations center. As has been mentioned, CPH brought in additional drone-tailored surveillance equipment the next day which has more capabilities like radar and optical classification (idk if it has lidar or laser range finding, or if radar is the only range finding it has), which suggests that the equipment CPH had was insufficient and needs to be supplemented.
HOWEVER, the media reported DroneSentry-X was despatched to Copenhagen airport the following day, that is not a good sign, this suggests the airport was without even a fairly basic counter drone system, maybe it just had DJI AeroScope or maybe no C-UAS at all.

But in this case what is alleged is a large fixed-wing drone, not a small quadcopter, and I think this point might be missed a little bit in that memo. A large fixed-wing drone with lights all over it which an employee initially thought was a small very-low-altitude plane (easy to detect), is an entirely different situation from a small rotor drone (hard to detect). If multiple such drones did fly over the terminals at ~100-120 meters, one would think ATC staff looking out at the runways would very easily see this aircraft. And it would be detected by some means other than visual sighting. The fact that Danish government officials are saying they have not seen any concrete evidence for strange drones, or any drones over CPH on 22 Sep, is telling. The fact that the airport has not provided any camera footage is telling. And the fact that an airport employee provided reporters from TV2 with footage of the small training plane that they thought was camera footage of the drone, and the report to ATC coinciding in time with this flight which an employee thought was a drone, is also telling.
 
I would lean towards saying this is unlikely, because other planes also took that approach path from the W/SW, and that plane would be easily identified by ATC. But who knows. It's getting increasingly hard to judge what is "unlikely". I think we can infer from the previous "drone" incident at Aalborg that the Danish police/military do fly helicopters with ADSB/ModeS turned off so they do not show up on FlightRadar24 or ADSB Exchange. There is a military air base in Aalborg attached to the civilian airport.

Well we know that there was a police (or military) helicopter flying around CPH at about 10.30 local time, from the news reporting (and the video from the Norwegian plane), and that definitely didn't show up on any ADS-B sites.

As for the approach pattern, isn't the unusual aspect the fact that the flight was heading almost due north for a time, towards the airport, and therefore would have appeared stationary? That's what @ThomasH was flagging up I believe - if you compare JTD468 to the VKG1095 track you posted, tou can see that the latter was always moving laterally as viewed from the north, whereas the former would have appeared to "hover" for a while.

And as we have seen from the Gothenburg incident, even if ATC are aware of a plane, they don't necessarily dismiss drone sightings relating to the plane.
 
New article from a Danish newspaper.
I had a photo from the paper version OCR'ed and translated with ChatGPT:
----------
When Copenhagen Airport examined radar system data following the drone reports on September 22, they obtained documentation of what staff had seen with their own eyes that dramatic evening.


The airport has not previously described this documentation in detail. Not until now.


The processed data showed lines on a map — radar tracks from objects that had moved in patterns with sudden V-shaped turns. Movements that neither birds nor airplanes can perform.


"It's drone behavior," says Morten Eli Lyngbæk, head of crisis management at Copenhagen Airport. He adds:


"You can see that it turns in the air in a way an aircraft could never turn. A bird wouldn't behave like that either."


Until now, Copenhagen Airport had avoided giving details about what concrete evidence — besides eyewitness accounts and video material — they had. In the two months since the incident, doubts have grown about whether there were drones at all that forced the largest airport in the Nordics to shut down for four hours.


If that were the case, it would look bad, since the observations did not only lead to the airport shutting down but also caused top-level authorities to speak very seriously about the drones.


For example, Copenhagen Police spokesperson Jens Jespersen spoke of a "capable actor" being behind it, and a few days later Prime Minister Mette Frederiksen said Denmark had been exposed to hybrid attacks.


The new information is based on radar data that "captures smaller objects in lower airspace," from which analysts have extracted the relevant tracks.


"With that, we can filter out everything like helicopters and airplanes and all kinds of birds. And then you see very clear traces of what is obviously drones," says Morten Eli Lyngbæk.


Kristeligt Dagblad has not seen the radar tracks, as Copenhagen Airport will not release the documentation, citing the ongoing investigation.


"A completely different matter"

The situation changes significantly for the drone case now that Copenhagen Airport's drone report is based on radar data. As defense consultant Andreas Graae from the Institute of Military Technology at the Royal Danish Defence College puts it:


"One should always be skeptical of eyewitness reports, but it is a completely different matter if they have radar data from a system that can distinguish between aircraft and drones. I'm not going to dispute that," he says.


The same assessment comes from Aalborg University professor Preben E. Mogensen, who researches the protection of critical infrastructure in the new drone reality.


"With the knowledge I have, I wouldn't doubt for a second that the airport's statement is correct," he says, adding:


"There's been a lot of talk about training aircraft, but they cannot move in the same patterns as drones."


Copenhagen Airport states that since September 22 they have acquired new equipment that allows them to proactively detect unauthorized drones, instead of having to identify them afterwards in radar data, as was the case this time.


Stars and sky observations

The doubt that has grown in recent months may be due to the airport's decision not to release documentation.


At the same time, a few weeks after the incident the government began speaking of "airspace observations" instead of "drone observations." Several media outlets described how a training aircraft had flown over the airport shortly before the shutdown and suggested this might explain the incident.


Asked why Copenhagen Airport has not simply presented the documentation if they want to put the speculation to rest, Morten Eli Lyngbæk replies:


"Of course we are not releasing material that the police use in their investigation. There is an ongoing investigation and we want to respect it."


Researcher in emergency management Rasmus Dahlberg still believes the public needs to see the evidence from the airport.


"I'm not trying to promote conspiracy theories, but I still haven't seen any official statements where the evidence is shown," Dahlberg says.


And the authorities may struggle to dispel the growing theories, because they are already spreading widely — and that comes with a somewhat bitter irony, Dahlberg notes.


"When doubt and insecurity arise in the population, hybrid attacks achieve their purpose.


"There are intelligence cultures that prefer to keep everything secret, but in doing so they serve the adversary's interests by giving space to alternative explanations and portraying themselves as an incapable actor," he says.

I find it strange they only found out afterwards, when they said the first day they had proof.

Radar alone wouldn't be conclusive of a drone, airport radar isn't even setup to detect drones.

Counter drone systems have radar configured to detect drones but they'd also have RF & EO/IR for confirmation.

I'm with Rasmus here. To me this smacks of a face-saving exercise. There seems to be no reason the airport couldn't share the data, even in partially redacted form.
 
It sounds like BS to me, Thomas. "V"-like movements on a plotter do not characterise drones, they do characterise lack of data though, gaps so to speak. Happens all the time, on all types of "radar" screens. And I am pretty sure CPH didn't have or use secondary ATC radar the night in question, nor more precise ditto that could actually spot these "V-turning" drones (again, it doesn't add up*)... They got proper drone-detecting equipment a few days later, and the "drones" have never returned since. Mm-hmm.

* First they're huge, fixed-wing type drones and everyone draws parallells to the ones crashing in Poland etc. But at the same time, unlike the actual drones over there, these for some reason have ubiquitous positioning lights and linger on for hours on occasion, so actually they gotta be huge VTOL drones rather, considering the loitering and supposed V-like maneuvering, but they have an endurance unheard of, and make no sound. It just keeps going on like this, one statement after another that simply do not add up.

The folks who think these "drones" are extraterrestrial craft and that they defy physics and common knowledge due to their unfathomable alienness actually have a better case. I mean, at least that adds up.

The vagueness of the term allows for maximum confusion between the source of the report and the person receiving it.

I wonder if it's possible to get an actual copy of the instructions given to the airport personnel regarding the reporting of security problems. Assuming they exist, the procedures you teach to a baggage handler should not be classified information.
 
This is a really interesting read about why conventional airport radar isn't suitable for detecting drones (and how specialized micro-doppler drone radar systems work):

(Use Archive at your own discretion.)

I've translated a small excerpt:

"This doesn't work for smaller flying objects. While regular radar can easily detect an airplane or, for example, a cruise missile, it doesn't detect smaller objects like birds or drones. The radar waves are so large and energetic that they essentially ignore these small objects. They pass unnoticed and only bounce back when they hit a larger body, like an airliner."

It's fascinating to see how the physics of radar inherently limits its ability to track drones, which explains a lot about current airspace security challenges.

Thank you!
 
New article from a Danish newspaper.
I had a photo from the paper version OCR'ed and translated with ChatGPT:

Can you provide the name of the newspaper and the publication date? Is there no online version? I agree that this story does not sound convincing. Initially it was an eyewitness who said they saw something they thought was a small plane, who then concluded it was a large drone, at which point they raised the alarm. Now we are supposed to believe that an object was detected later when sifting through airport radar data, which was distinguished from birds and helicopters and planes, and therefore must be a drone. There is no valid justification for them not releasing this raw data. "it's part of the investigation" is not a valid reason.

This came up when I googled some sentences, but I have not paid to get past the paywall to check if it matches. It might be returned from Google just because it uses similar language.

Researcher in emergency management Rasmus Dahlberg still believes the public needs to see the evidence from the airport.

"I'm not trying to promote conspiracy theories, but I still haven't seen any official statements where the evidence is shown," Dahlberg says.

And the authorities may struggle to dispel the growing theories, because they are already spreading widely — and that comes with a somewhat bitter irony, Dahlberg notes.

"When doubt and insecurity arise in the population, hybrid attacks achieve their purpose.

"There are intelligence cultures that prefer to keep everything secret, but in doing so they serve the adversary's interests by giving space to alternative explanations and portraying themselves as an incapable actor," he says.
Dahlberg highlights the issue here. Substantial claims were made and never backed up by evidence. Data was an is available (either in favor of or against the official narrative), but continues to be willfully withheld by authorities. The concrete pieces of data that have surfaced fall into 3 categories:
(1) certainly not a drone
(2) nearly-certainly not a drone
(3) maybe a drone, maybe not, but there is significant reason for doubt

If there is a category (4) "definitely a drone", it is odd for all of that data to be withheld, leaving the public only with data buckets 1-3. It is also odd (not that odd) that in every case of a drone panic, this exact same thing happens. The public gets stuff which falls into buckets 1-3, and then the drone/UFO narrative survives on the basis of people saying category (4) exists but is all being kept secret. And authorities make it worse when they do actually keep stuff secret that they don't need to.

The airport authorities say they have conclusive concrete proof that there were drones, but even their description now is poor, and it's been two and a half months. And when asked by reporters (and apparently also by politicians), they have not provided this evidence and said they will not release it. There is no reasonable justification for refusing to provide information of this form, that involves no privacy or sensitive secrets, that would clarify widespread public concerns. This phenomenon of authorities simply refusing to release data/info that they could release, is too common and people should be mad about it. They try to justify it by saying it's relevant to an ongoing investigation or it falls under some national secrets law, but neither of these make sense in cases where releasing the data actually helps the investigation, and helps national security. It is bad for national security to have the population generating so many false-positive reports, and suffering from undue paranoia from an incorrect understanding of events for which contrary/clarifying facts are being withheld for no good reason.
 
I can't find a separat thread about the "Køge Drones" from January 3, but I've now identified all of them as: ......tadaaa PLANES.

Sorry I think the video got a bit messy and my AI voice didn't say the word's I'd like to say right, but anyway a few people sees it, so F it.

I forgot to include these quotes from when the witness was on a podcast.

1 . They had a frightening resemblance to the New Jersey drones.
2. In terms of size, I'd say the big ones were about the size of a small passenger plane.

No way! :D
 
Here's an update from Norway with regard to the 2025 'drone' sightings (source: VG):

Norway's domestic security service PST investigated a large number of reported drone sightings across the country in 2025, including incidents near airports, military facilities and other critical infrastructure. According to the agency, none of these cases could be linked to foreign states or intelligence services. In many instances, the reported "drones" turned out not to be drones at all, but stars, aircraft or other aerial phenomena.
