Many years ago a PPL buddy & I were doing a leisurely (& almost certainly illegal) practice approach to the disused Gaydon airfield in the UK Midlands in a PA28 . At approx 200 feet AGL we were just about to break off the approach and turn away when two Harriers in line astern passed under us doing a great deal more knots than we were making. They were following the ex-V bomber base runway heading en route to the Welsh valleys. We drove home without saying a word to each other & never went near Gaydon again.
I've often wondered whether they had actually seen us...
