One of my abiding low-level flying memories is of standing on the dam wall of a small reservoir somewhere on top of a moor in the Yorkshire Dales near Buckden, doing a spot of flyfishing. Looking down the valley I saw this F1-11 heading up the valley without a sound and it flashed overhead at minimal feet - I was then knocked over by the jet-blast and nearly fell into the water!!!!
Bloody marvellous it was!!!
