Not really. It looks like a bright IR flare you'd expect from any engine type heat source. What exactly are you comparing it against?Looks more like the Tic Tac.

well, just to clarify.. Fravor did not engage with "THIS" object. (FLIR footage). This footage came from youtube a few years back. There really is nothing to (at all) to verify this footage is even from that day.But the fact that a leader of a navy fighter squadron described engaging with this object
The jets were circling around the area not crossing over it though?However the jets themselves were also travelling at around 250 knots (422 feet per second) at 10,000 feet, looking down at a moving object at 1,000 feet. It's literally impossible to describe this at moving over the disturbed water. It could only possible have lined up for a fraction of a second. Here's a side view of the movements and relative positions for 1 second.

It makes no sense. You can't say it was going across the region if it only happened to be lined up for a fraction of a second - a fraction which is entirely depending on the position of the jet as well as the UFO.
Well there's a claim of chain of custody, but obviously being "top secret" we haven't seen thiswell, just to clarify.. Fravor did not engage with "THIS" object. (FLIR footage). This footage came from youtube a few years back. There really is nothing to (at all) to verify this footage is even from that day.
Fravor says he engaged with "an object", not "this object"that doesn't read right, as Fravor does seem to push this footage is of what he saw. so..
so... Fravor's story is about "an object", not necessarily "this object".
That makes no really difference. At 400+ feet per second a circle would be a few miles wide, and just a gentle curve instead of a straight line.The jets were circling around the area not crossing over it though?

I recently watched some youtube videos taken above sea from an F18 cockpit. It surprised me how wide and clear the view is and how calm the ocean looks. On a bright day in calm weather I think it is actually quite easy to spot an object, keep it in view while descending, and to assess its appearance from the cockpit.
How do you mean they are consistent? (If I understand you correctly Vc is how quickly the jet is closing in on the object.)Note that 400 kts True Air Speed (TAS) is consistent with the jet's Calibrated Air Speed (CAS) of 250 kts shown in the ATFLIR display
How did you come up with the angle 45° ?Note that 30 feet is the size of the object image but the object itself is rotated with respect to the FOV plane. So S=30 feet means that the actual object length is approximately 40 feet (roughly 30/(0.5*sqrt(2)) when the object is rotated 45 degrees with respect to the FOV)
The angular size as a function of t isIf a constant closure speed Vc is assumed for the whole 20 s video segment, the angular size α of the object as a function of time will be:
α(t) = S/d(t), where S is the actual object size and d(t) is the distance to the object as a function of time.
I believe you should calculate the angle asI calculated the object's angular size by computing the ratio between the visual object size and the total FOV size for each snapshot (separately in x and y since the video is slightly asymmetrical). Knowing the actual angular FOV of the ATFLIR (0.35 degrees in both x and y at zoom level 2) I could calculate the actual angular size of the object for each snapshot by simply multiplying this ratio by 0.35 degrees.
Fravor has said the water disturbance was the size of a 737 (see video below @ 2m 35s) which has a gross area of 335 square feet (see http://www.b737.org.uk/techspecsoriginals.htm) and also that the object was going back and forth acoss it not just crossing it once. But yes that's not what "Source" said but isn't that person in the 2nd plane that remains at higher altitude and is also a less experienced pilot? Also, the Source account is 2nd hand reporting which I have seen being dismissed as unreliable earlier in this thread, whereas Fravor is 1st hand.That's not the issue here. The issue was the description of the object being at 1000-3000 feet and "crossing" an area that was 80 feet wide.
How do you mean they are consistent?
(If I understand you correctly Vc is how quickly the jet is closing in on the object.)
How did you come up with the angle 45° ?
So I guess it works anyway.
what? what am I missing here? Fravor didn't take that video. At the very least, if we assume it was actually taken the same day, it was 3 or 4 hours later and the pilots who took the FLIR (according to Fravor) didn't see it visually.Yes, but allegedly the object was hovering when this video was recorded.
OK, but the closure speed would be the difference of the jet speed and the objects speed: Vc = Vobject - Vjet .I used this TAS calculator: http://indoavis.co.id/main/tas.html and filled in the altitude (20.000 feet) and CAS (250 kts) from the ATFLIR display. This yields a TAS of 385 kts
Where did you read that? The video was recorded by a second pair of jets/pilots later, after Fravor and Slaight had returned to the ship:Yes, but allegedly the object was hovering when this video was recorded. If the closure speed is in the same ballpark as the jet's True Air Speed this is an indication that the object was indeed hovering.
Source: https://coi.tothestarsacademy.com/nimitz-report/External Quote:According to Source, OK-4 and OK-5 also encountered the same object later the same day. OK-4 and OK-5 were assigned to the follow-on cycle from the U.S.S. Nimitz and obtained brief FLIR footage of the incident.
It's just an approximation based on what I see on the ATFLIR screen, see figure below. The exact angle doesn't change much to the end result since the whole exercise will only give you approximate values. That's why I rounded the numbers for the object size to 30 and 40.

Fravor is retired and talks about it, maybe the other pilots are still in the service. Joking when back on a ship is one thing but to start faking stuff using military technology to make fun of your squadron leader seems an unlikley level of indiscipline. They were also apparently debriefed by their intelligence officer at the time if the report that's been circulated is genuine under the heading F/A18 F FLIR Tracking:what? what am I missing here? Fravor didn't take that video. At the very least, if we assume it was actually taken the same day, it was 3 or 4 hours later and the pilots who took the FLIR (according to Fravor) didn't see it visually.
And since according to Fravor all the guys on the ship were making fun of him, isn't it more probable the next crew took FLIR footage of one of their own planes, zoomed in to get the 'fly off fast' effect and presented it to Fravor as a joke? We've never heard 'boo' from the pilots who took that footage.

Source: https://fightersweep.com/1460/x-files-edition/External Quote:As Dave was pulling for nose-on and trying to get a dogfight lock with his radar, the AAV tightened its turn, "lift vector on, then aft" as Dave described, passed behind his tail and accelerated away at multi-Mach speed. Dave immediately queried Princeton for a snap-vector but the SPY-1 radar had also lost the contact. The first calls from Princeton were "picture clean." A few moments later Princeton came back with, "You're not going to believe this, it's at your CAP." Princeton had picked up the AAV hovering at 24K at the assigned Lat/Long Dave had used earlier during training as his orbiting point.
Though low on gas, the FASTEAGLE flight swung through the CAP position to try and pick up the AAV again. They saw nothing more on their way back to Nimitz. Even the 100 meter circle of turbulent ocean water had disappeared. That spot was now indistinguishable from the rest of the sea's surface. Asked later, Dave reported that he had not seen anything on or below the surface of the ocean that may have caused the turbulent circle of water. It had existed when they had first visually acquired the tic-tac, then was gone when they circled back a few minutes later.
Back on Nimitz after recovery, the four crew headed down to the paraloft to remove their gear. The next four crews from VFA-41 were getting dressed for their training mission to the same area, using the same assigned Lat/Longs as CAP points. Dave and his crewmembers passed on what they had seen to the new guys and reminded them to get tape if they could.
By the time the new crew launched, rendezvoused and checked in with the E-2 for control, it was early afternoon; 1500. The planes separated, with one heading to that same southern CAP location. They were cruising along at 20K and 300kts, max endurance. Again, the jet, radar and also, this time, the FLIR were spanking new and operating perfectly.
The WSO first picked up a contact on the radar around 30nm away while it was operating in the RWS scan mode. He checked the coordinates and it was indeed hovering at their precise CAP point.
At the very least, if we assume it was actually taken the same day, it was 3 or 4 hours later
OK, but the closure speed would be the difference of the jet speed and the objects speed: Vc = Vobject - Vjet .
TAS is only a measure of the jet speed relative to the air, if the object is moving the two are unrelated. Even if the object is stationary (relative to ground) TAS might differ significantly from the speed relative to ground. Only if the object is moving at the same speed as the air where the jet is flying this would be the same value (unlikely).
I don't see the 45° in the video at all. It could be any angle really. (Based on the examples of FLIR footage from other known cases it seems hard to discern even the basic shape of an object based on only the FLIR footage.)
Given that it could be rotated any angle relative to the jet, any value for S (the apparent size) between say 5 and 50 feet could be said to be consistent with the story, and that would mean any closure speed between -70 to -700 knot, and distance of 1.6 to 16 NM could be said to be consistent with the story as well. And that is even without considering the uncertainty in the calculated values!
That is a lot of "if"s to begin with. At the same time you say it was hovering, so then the airspeed relative to ground at that altitude would have had to be zero. And if you read the paragraphs below the one you quoted from the fightersweep article: "it was a few thousand feets below" them. I find it unlikely that the TAS would match the closure speed.Why is that unlikely if they both reside in the same layer of air, at approximately the same altitude, at 10 NM distance from each other?
I disagree. I can't see how the footage gives any indication of the object's rotation. Even if we assume it was roughly pill shaped it could have been rotated at almost any angle relative to the jet.The IR part of the footage gives a good impression of the object's rotation with respect to the FOV plane:
Well, yes, if the apparent size is X then the true size must be equal to or larger than X.If you measure 30 feet from left to right, the object cannot be smaller than 30 feet as can be seen in the figure below.
The author of that article is also an ex fighter pilot, and apparently he thought the FLIR recording, in itself, was unremarkable. So again: the only evidence we have indicating something remarkable happened is Fravor's and Slaight's eyewitness accounts.External Quote:Somehow the tape made its way to YouTube. A few years after the incident, when first telling me the story, Dave pointed me to the link. It was unremarkable without the background information.
I find it unlikely that the TAS would match the closure speed.
I disagree. I can't see how the footage gives any indication of the object's rotation. Even if we assume it was roughly pill shaped it could have been rotated at almost any angle relative to the jet.
The change in apparent size based on rotation also gives another source of error here; the object could have rotated slightly while being recorded. So the apparent change in object size might be because of changing rotation as well as changing distance.
I forget where I originally saw it. But it's also in the latest TTSA "document" released.From where did you get the 3 or 4 hours?

Thanks, yea I saw that unsourced document by TTSA, but your wording made it sound like the pilot said it was hovering.The object, according to the FLlR, appeared stationary. There was no discernible movement from the object with the only closure being a result of the aircraft's movement.
The closure speed is Vc = Vobject - VjetWhy? Do you have any data that shows that wind speeds at sea, at 20.000 feet, on a bright and sunny day, vary considerably over a distance of 10 NM and an altitude difference of 1 NM? Or do you just 'find it unlikely' that they don't?
I really only see a fuzzy elongated (horizontally) blob. I don't understand how you get 45 degree from that, not even if you assume it is tic-tac shaped (and that blob looks too thin to be a tic tac btw). Yes, depending on the angle and the real size the apparent size could be 5-50 feet (smallest if it is pointing right at you, largest if it is pointing 90 degree to the line of sight).To my eyes it is clearly rotated but maybe your eyes see something different.
I try not to assume anything.Yes, you can invent other narratives that are also consistent with the video, I already pointed that out in my analysis. But why would you assume that a self-invented narrative that contradicts the original narrative is closer to the truth?
The original narrative tells that an object was approached that did not show any apparent movement, and this is not contradicted by the video. Only in case of clear contradictions I would be inclined to change the story.
The closure speed is Vc = Vobject - Vjet
You have calculated an estimate of Vc based on your measurements of the apparent size of the object seen in the FLIR video. But you don't know the speed of Vobject, nor of Vjet. The best we have is an estimate of true air speed (TAS) for the jet, but that is not the same as the speed over ground (it can vary at least as much as +/-200 knot). And we don't know what Vobject is at all.
I.e. Vc is not the same as TAS of the jet.
I.e. Vc is not the same as TAS of the jet.
But you haven't answered my question yet:External Quote:Only if the object is moving at the same speed as the air where the jet is flying this would be the same value (unlikely).
Yes, depending on the angle and the real size the apparent size could be 5-50 feet (smallest if it is pointing right at you, largest if it is pointing 90 degree to the line of sight).
The problem is that the result you found is consistent with both the story being true and not being true, so it doesn't really tell us anything. The uncertainties are so large it would be consistent with almost anything mundane.
If you want to distinguish between e.g. three theories, a test that is consistent with all the theories doesn't help us single out which one is correct.
You also have to account for the angle. V denotes a velocity - i.e. a speed in a specific direction in the air. The speed of the jet in the reference frame of the object and the closing speed of the jet towards the object are different things if the camera angle is non-zero.
I forget where I originally saw it. But it's also in the latest TTSA "document" released.

Shouldn't you be the one providing evidence that your assumptions are valid?Do you have any data that shows the wind speeds at sea, at 20.000 feet, on a bright and sunny day, vary considerably over a distance of 10 NM and an altitude difference of 1 NM?
I don't think we should pick one. We have different possibilities and we could assign each a probability. When we get new data we could look at how that data affect the probability of each of the different possibilities and adjust them accordingly. That is hard to do in practice but it can help us reason about the value of new data. If we get new data that affect all the possibilities in the same way, that data won't affect any of the probabilities.If several theories fit the same data, why not pick the one that is consistent with the narrative of the witnesses
The assumption here is that these were the F18's piloted by Fravor and Slaight, but the time does not fit so these must have been different jets
and from this new 'document' that has no headers attached or dates.External Quote:As Cheeks approached the spot he was being vectored to, Princeton advised him to stay above 10K as the section of Super Hornets were approaching the target https://fightersweep.com/1460/x-files-edition/
In the meantime [Jeremy Corbell] managed to interview one of the radar operators. It's hard to tell check his identity since he wants to remain anonymous, but for what it's worth:
He did the morning shift and kept on seeing anomalous objects on his radar screen during his entire shift. They were not treated very seriously (but apparently - from the report discussed above - some jets were already sent to the area to check it out).
His shift ended around noon, but a couple of hours later he was invited to watch video footage. According to him it was different footage than the FLIR1 video, much clearer, and what he allegedly saw was quite spectacular.
The video he describes sounds like Fravor's UFO chase, but Fravor himself never mentioned that video. Fravor commented to CNN about the FLIR1 video: "When it leaves the screen on the video, it's moving pretty fast."External Quote:The following events took place during deployment preparation of the Nimitz Carrier Strike Group (CSG) during the months of November and December 2004 in the SOCAL Operating Area off the coast of California and Mexico. The CSG was comprised of the following ships and submarine: USS Nimitz (CVN-68), USS Princeton (CG-59), USS Chafee (DDG-90), USS Higglns (DDG-76), and the USS Louisville (SSN-724). The Nimitz was home to Carrier Air Wing 11 (CVW-11) comprised of VMFA-232 (USMC F/A-18C), VFA-14 (F/A-18E), VFA-41 (F/A-18F), VFA-94 (F/A-18C), VAQ-135 (EA-6B), VAW-117 (E-2C), HS-6 (H-60), and VRC-30 Det 3 (C-2A). The only participants in the events surrounding the detection and intercept of the AAV are the USS Princeton, VAW-117, VMFA-232, and VFA-41.
so... both accounts (pdf document and article) can't be true. The fighter sweeper article puts Cheeks and Dave together.
A radar operator on the Nimitz, not the Princeton? We previously discussed a Reddit post that cited a radar analyst on the Nimitz, but the Executive Report doesn't list the Nimitz among the participants
The video he describes sounds like Fravor's UFO chase, but Fravor himself never mentioned that video. Fravor commented to CNN about the FLIR1 video: "When it leaves the screen on the video, it's moving pretty fast."
I see no discrepancy between the fightersweep article and the pdf document.
Another possibility is that the two low flying jets saw something and reported it to the Carrier Intelligence Centre but Fravor was unaware of this. Note that these two other jets were both flying low, while during Fravor's flight both jets came in high, only Fravor flew low and Slaight stayed high so these really must have been different jets
I even suspect that the 'official report' may have used some information from the fightersweep article.
The radar anomalies that the Nimitz radar operator reported during his morning shift were basically ignored so no, the Nimitz did not seem to have played an active part in the intercept that afternoon.
The radar operator was especially impressed about an upward motion, not a sideward motion of the object.
According to the pilot report published on TTSA's website, there was another video. Maybe not from Fravor's helmet but from a gun camera mounted on his F18:
If such footage exists, Fravor might not be allowed to mention it. (The FLIR1 footage was leaked to the internet some years ago, there was never an 'official release' of this footage by the DOD to my knowledge, so he might as well talk about it now.)
So I enhanced the contrast/brightness of the TV part of the video a bit and went through if frame by frame. To my surprise you can just discern the top part of the object in some of these frames, and the shape that emerges matches a tic-tac very closely. It also matches the shape that emerged from Ian's combination of TV and IR (the last two pictures).
