F.E.D. That incident happened on Provosts IIRC. ( N.B not J.P.s)
Around that time another middle-eastern country, which will be nameless, had pilots attending more advanced training during which an instructor was overheard advising a student that on first seeing enemy fighters it was a good idea to "fly straight and level for a bit" until he was sure of what was going on.
Taken aside quietly he then explained:
" Think about it. It's highly likely we will up against these b*ggers in a couple of years time"........
