What was in the skies above Jersey (CI) yesterday, any ideas?

Where are they testing the BAE Taranis platform these days? It is purported to be Mach 1.0+ and I bet it can turn like that at that speed as well with no pilot. Nice way to test a stealth UAV would be to sneak up on commercial traffic and do some jinky maneuvers to see if would be detected... Could be X-47B as well.

S&F...Dont know any of conventional Aircraft that could make that turn and spew out a vapour trial.

Very odd indeed

Very impressed by your fast reaction, Wish it was me acting as fast as you.
Then my first thread would not have ended in the grey area
After my incident the camera is now always ready nearby with GPS , time and date on the pictures.
Happy to have you here and a good second thread. S & F

I am sure this guy can pull some WTF maneuvers when needed. They may also be testing something else, you never know.

How do you know a "WTF maneuver" was responsible for the contrail without knowing the flight path in 3D? A wide, gentle 180 degree turn can appear as a sudden reversal of direction when the contrail is viewed from the right perspective.
