Trail that forms curving shapes

Some days we have plains going over with nothing behind them. Some days there are plains with a short trail that follows them, staying the same length. Some days the plains leave the skies full of persistent trails that go on for miles and stay for the entire day. These eventually merge together causing the skies to become overcast or hazy.

I am concerned but nothing would make me happier than if this could all be put to bed as nothing but water condensation and not some weather altering experiment with hazardous health repercussions. I am aware that the "stuff" that is in the "chemtrails" is making its way down to earth and slowly but surely contaminating our water and food supply by entering the soil. However ... i am wishing for hardcore unbiased evidence from an independent source to put my mind at ease. Unfortunately i don't trust anyone anymore due to the fact that everyone who seems to have an educated explination happens to have a financial interest in this contravetial subject.

After capturing this on my way to the shops i became insanely irritated, confused and betrayed. i don't get this at all!!!What is the best explanation for this "persistent" trail????????????IMG_2683.JPG

Hi Celeste- Can you share with us how you are aware of this? ...how "sure" are you?

well theres 'soot' type stuff and what not, just like cars.

Carbon residue, yes....from the fact that the fuel is a hydrocarbon, petroleum-based energy source.

Modern jet engines are very, very clean burning, actually. Still, there is a modicum of pollution. Of course, your typical diesel semi tractor-trailer truck is a lot worse. (Or/and, diesel-fueled railroad locomotive). Etc. Did I mention the guy who mows his lawn with a gasoline-powered mower? Or, the millions of gas-powered leaf blowers used by countless yard clean-up crews?

I think Celeste needs to be a little more specific about her concerns before we need start delving into the composition of jet exhaust.

Apparently @Celeste has not return to Metabunk since she started the tread. Lacking the information on where and when the OP picture had been taken, I and @Trailblazer instead entertained ourselves by exploring the 'rude' Scottish trail from my post (#4) above.

As there were no high altitude commercial flights above that particular area, the contrail almost certainly was left by a military plane, the identity of which remains unknown to us. However, it was possible to investigate whether the contrail shape was drawn deliberately, as alleged by the media reports, or it was just an accident, as the RAF officials said.

In order to establish the actual position and dimensions of the contrail, we have identified the locations of both photos at the outskirts of Bishopmill, Elgin. Their viewing directions (NE) are nearly perfectly aligned, the second photo was taken some 500 meters behind and very short time after the first one. Modelling the trail parts after the photos have been added to Google Earth showed that the contrail was above the sea, some 15 miles away from the shore. The contrail was more than 30 miles (50 km) long, with the turn diameter being about 6 miles (10 km), and its closest end was about 25 miles away from the cameras. The distances are for the contrail altitude of 10 km.

To confirm that the contrail shape could have resulted from a plane flying a racetrack pattern, a matching shape has been generated on the Contrail Pattern Simulator by @Mick West. The simulated pattern has been added to Google Earth, using the modelled contrail parts as guides, and raised to the altitude of 10 km. It matches well the visible part of the observed contrail. Its most distal part either was hidden behind the cloud or did not persist:

Therefore the results of this analysis 'exonerate' the RAF pilot from the wrongdoing. The KMZ file for it is attached to this post.

The racetrack pattern that in combination with a strong SW wind produced this contrail shape is about 50 miles long, which is not unusual for military contrails. I recall seeing a similar racetrack pattern off the British coast on one of the Terra images:

and just this week my 2 daughters flew to UK london watching their flight while landing they did bit of circle work.

THAT is one of the many benefits of both "FR24" and/or "FlightAware"!!! The ability for those on the ground (or, if "WiFi" enabled, in the air too) to track loved ones or friends (or "whatever" ;) ), en-route.

Welcome to the 21st Century!!! :)

AND this shows clearly the ridulousness, the abject lack of substance of the "chem"trail myth, and hoax!

Sorry if this has been mentioned before, I did look and didn't find it, but i wanna mention that the area described above isn't far from RAF Lossiemouth, one of the UK's biggest and most active airbases. I i suspect a training flight.

Looking at FR24 the other day I saw the craziest flight path I had ever seen on there. There was a plane flying near Salisbury that taken off from near there and popped down towards Ilminster/Chard and flown all over the shop before returning to meander round the Salisbury area.

The fact that the plane belonged to Qinetiq and was part of the Empire Test Pilots School (based at Boscombe Down) probably explained all that though. it was only at 5000ft when I looked at it so no weird contrails to see.

The weirdest flight paths I see cropping up on FR24 tend to be gliders flying over the North Downs near my house. Certainly no contrails there!

Back to the OP, it is not unusual to be in a holding pattern, begin the out bound leg and to have holding cancelled and be told to continue original tracking by turning back to the holding fix. This is what I suspect happened with the middle, smaller, almost circular trail.

don't think that's a contrail in the traditional sense. I think the glider there is dropping water ballast

Modern competition gliders carry jettisonable water ballast (in the wings and sometimes in the vertical stabilizer). The extra weight provided by the water ballast is advantageous if the lift is likely to be strong, and may also be used to adjust the glider's center of mass. Moving the center of mass toward the rear by carrying water in the vertical stabilizer reduces the required down-force from the horizontal stabilizer and the resultant drag from that down-force. Although heavier gliders have a slight disadvantage when climbing in rising air, they achieve a higher speed at any given glide angle. This is an advantage in strong conditions when the gliders spend only a small amount of time climbing in thermals. The pilot can jettison the water ballast before it becomes a disadvantage in weaker thermal conditions. Another use of water ballast is to dampen air turbulence such as might be encountered during ridge soaring. To avoid undue stress on the airframe, gliders must jettison any water ballast before landing.

mind you some of these ballast dumps can look like contrails at first glance




(PS - @M Bornong - not saying for a minute that you were suggesting that your photo did show contrails, just pointing stuff out for the casual visitor)

Thanks, I didn't know gliders needed ballast. I learn something new everyday by coming to this site.

Déjà vu

A year ago (November 7, 2014) a racetrack contrail in Scotland created a stir propagated by local media and British tabloids:

This flickr photo, showing a similarly shaped contrail, was taken on December 7, 2015 (location unknown).
2015-12-07_15-31-54 by Ben W., on Flickr

PS There are more pictures of this and similar contrails in Ben W. photostream, taken on the same day.

Russian Sukhoi fighters over Syria flying racetrack patterns during combat air patrols. Believed to be the recently deployed Su-35S.

Here's some background to another bit of juvenile "sky art" over Washington state in 2017: https://www.navytimes.com/news/your-navy/2019/05/14/the-navys-probe-into-sky-penis/


It prompted viral guffaws from some and online outrage from others.

There are shot glasses commemorating the event and it birthed memes ahead of the annual Army-Navy game.

But the inside story of how an EA-18G Growler jet crew drew a penis across the clear blue skies of Washington state in 2017 has never been told.

Until now.

It was the work of two junior officers with the “Zappers” of Electronic Attack Squadron 130, who had sky time to kill and noticed that the white contrails their jet produced were particularly robust that afternoon.

But they never counted on those contrails lingering long enough for folks on the ground to see their phallic rendering, according to a copy of the military’s sky penis investigation obtained exclusively by Navy Times.

From a chemtrail debunking perspective this part is relevant:

“I could definitely draw one, that would be easy,” the pilot boasted. “I could basically draw a figure eight and turn around and come back. I’m gonna go down, grab some speed and hopefully get out of the contrail layer so they’re not connected to each other.”
[...]
Soon, the EWO reported they were definitely “marking.”

They had found the sweet altitude, and the contrail sky penis was being born in their wake.

The pilots understood that they could generate contrails only in a fairly narrow band of altitude.
