You have to admire Sir Michael Bishop's judgement of the IT market, namely when to dip in and out.
BMA's "Instant Airline" product won them a Queen's Award For Industry. They wet-leased to Sudan Airways, Syrian Arab, and PIA (I think). I seem to recall having a Syrian Arab sick bag to store things in as a teenager. And not vomit.
BMA's fleet were all very much bespoke-painted, to the extent that some of the "nines" show quite different characteristics of the font. Ernie Robey, the painter seemed to be quite able to master other liveries, too.
