Flyboys having fun

Didn't come out as clearly as I hoped, but these contrails made it look like someone was really having a fun time today.

(Stopped the car on the way to a meeting in Edinburgh. Almost phoned to cancel the meeting, as it was such a lovely day I just wanted to go an walk the dogs...)

PS - is a cheat to put something in for an Assignment if you took it the day before the assignment was announced? If so - sorry!
