In the early years of the 720Bs almost all flying was Luton based and they had 4 Britannias as well until 1972. They starting flying more from Gatwick once the late Alan Snudden came in from Dan Air.
The BY fleet was always more dispersed.
Stands were not as formal then as they are now. Aeroplanes were often packed in a way more akin to a car park round the Court Line hangar for example.
This might be better continued on the AH&N thread.
