It was one of the last airshows at West Malling. I was standing in the cockpit of the Sally B B-17 watching the Vulcan lead the Reds down the runway at 100'which was an absolutely fantastic sight. My girlfriend started screaming as she was standing in the bombay and the Fort was vibrating so much from the noise that she thought they were starting the engines
Another fantastic flyby was watching the BBMF beat up Dartmouth College.
Best of all was the B1 at Mildenhall 8 or so years ago. Everbody was watching the current display but I spotted the B1 in the distance firing up his afterburners and sweeping the wings back. He went down the runway just short of Mach 1, setting off every car alarm in the place, there were kids crying and filling nappies while grown ups with their backs to the runway choked on their burgers and split their beer!
