In the 1960s as a very young child, regularly being woken by the Vulcan Concorde engine test flight from Filton early in the morning overflying our house and rushing to the window to see the huge Delta wing disappearing into the distance. The sight and sound of 3 Vulcans approaching low and then overflying me on the Yorkshire moors in about 1978 will never leave me. I can remember almost no other part of that trip.
