More nice photos. The picture of the ex-BMA aircraft reminds me that BAF/BWA made it their business to acquire every serviceable Viscount available, rather like Dan-Air with the Comets.
BA dropped the LBA-LHR route in April 1980, probably about the same time as they began the withdrawal of the Viscount fleet. One wonders if they'd have hung on to the route if the Viscount's days weren't numbered.
