At a gloomy, overcast air show at Gaydon in the late 1960s. None of the aircraft had remained in view throughout their routines, disappearing into the murk at the extremes of the display area. Then the Vulcan arrived and seemed to be on one wingtip or the other continuously and only going out of view at the end of the display with a thunderous climb into the low cloud base.
In 1977/78 I was working on the extension to Waddington’s bomb dump, i.e. on the far side of the runway from the ‘crowd line’. This meant we were directly underneath the frequent rehearsals during the display season, getting the full benefit of 4 Olympus engines directly (and low) overhead.
