anyone know why G-BFZL had no rear baggage door?
Those two Viscounts that TAA ordered, but didn't take delivery of, were specified with the optional lounge aft of the rear door, which had accommodation for 4 passengers, instead of the baggage hold and complete with a small window on either side, which can be seen in this 1978 photo of G-BFZL taken at EMA just after BMA had bought it.
I can't find any photos of it in BMA livery with the lounge windows, so it looks like they must have been blanked off before it entered service with them.
