'This was UFOs - I saw them': Mystery surrounds strange contrails that appeared over Grimsby

“i have the same picture on my phone that i took while watching the airplane circleing”

“I suspect the incident took place between 1300 and 1400 GMT on the 14th

Here is a radar image showing the culprit...an F15 from Lakenheath , one of a flight
which were carryng out tight turns . Notice in the image below the altitude constantly changes as it climbs and dives.

“Lakenheath is an RAF base with USAF tenant units for the time being. It's as much a US Air Base as Creech AFB is an RAF base.”

“Are their really people idiotic enough living in ne lincs to believe aliens crossed millions of light years of space to perform aerobatics in the skys over Grimsby , just exposes our inadequate education system”

“Awesome!!! Now the "ALIENS" have gone back in technology and are using jet engines for propulsion systems!! hahaha..thought they used anti-gravity engines which create NO contrails for the jet stream to drift them in this shape! haha whatever next ay folks? lol”

“"Was it aliens, UFO?
What a load of rubbish!
It was two RAF Typhoon aircraft performing flat turns or figure of eight turns between 24 and 35000 ft .
You could see them come up north ,start the turns and in the turns but only if you looked well in advance of the contrails they produced. Most of the trails were produced in the NE and drifted across the sky.
The craft in the video is one of the aircraft in a diving turn and then away to the NE at a much lower level. He/she would have been underside to the sun as he/she dived and you could see the aircraft. Then as he/she rolled hard left we lose him/her as aircraft went tail to sun and then caught him/her again as the aircraft came to straighten up out of the turn. Nothing unusual whatsoever.
An unusual event over land, nice to see, nothing to worry about but it was a shame they were not practising Fighter V Fighter.
That would have been dramatic!”

“Eurofighters..........'nuff said”

“If it was'nt aliens then who was that at my door ???”
