Hi
Thanks a lot for all the replies, it sounds like doing those low level flying runs must have been brilliant. It's fascinating that you used landmarks as waypoints. No GPS in those days I suppose.
250 feet is properly low! I remember at the time, one of my fellow primary school pupils swearing blind that he'd seen the hercules going under the wires of the national grid pylon, next to our school. :-) I suspect he was exaggerating *SLIGHTLY*
Thanks again for the stories guys, it really refreshes the memories for me.
