Sorry, I can remember several days when we took a lot of diversions but not many specifics. They just happened from time to time.
The first I remember is before I validated so pre-1971 when we took 45 diversions from Heathrow on a Saturday morning. We parked them everywhere, inc along the apron centreline from stand 9, 'first in, last out'. We asked McAlpines if they had any movements that day and could we park a couple of aeroplanes on their apron. 'Help yourself' they said so two Viscounts later . . . .
