Was at SAA at the time and true. Helped to pack up the analogue sim
i was at BMA until 1986 then Monarch
those 7 Viscounts were the backbone for many years for BMA
one of the ex SAA 7 was badly damaged in a crosswind landing at LBA in 1981
G-AZLT and she rebuilt with wings off G-BAPD or PE and re-regd G-BMAT!
BMA also bought 2 SAA 707-344A's (PW JT4) took them to EMA but they got sold on and scrapped I recall
we never used them in the end
they had full width leading edge flaps fitted i recall (non Standard on a 707-320/420 coal burner)
