I believe Roy is still the CEO at Scot AW, and Merlin is in charge of commercials. Brian Souter is chairman and has pumped money into the airline.
Roy was a QFI at Ipswich airport (now a housing estate) long ago and came up the air taxi way. About 15 years ago British Airways had an initiative to provide funding to minor carriers (god knows why) which Roy got to start Ipswich to Amsterdam.
The TV programme was I believe called "Darling lets start an airline", no doubt a reference to Merlin's commercial acumen (believe she's a qualified lawyer). It had footage of their first Dornier 228 with micro-sized flight attendant, she had to be under 5 feet tall. In flight meals were shown being prepared by a friend who did them in her home kitchen and delivered to Ipswich airport whence Roy flew them over to Amsterdam.
Scot did a big expansion at London City some years ago but then retracted somewhat and seem to be marking time. Their fleet of Dornier 328s is large for their scheduled commitments, but they seem to pick up exec charter work with them (football teams etc) as there is not much else available in the UK in this size. Oh, and they rarely seem to make a profit, so it's a bit of Brian Souter indulgence as well. Millionaire Souter lives near Dundee and on the Scot service from there to London he is one of the regular pax; would doubtless be an inconvenience to him if the service were lost.
They are still based at Cambridge despite having no schedules from there; it's their alternate if LCY is fogged in.
