Correct
swh, it was MSA then
, but I actually worked with ex AI pilots, by now B747 captains, who joined MSA at the time the B707s arrived. This was 1968 as they were doing circuits at Paya Lebar and the downwind leg was right over my house in Stevens Road!
AI used to do base training at Kai Tak in B707s, flying circuits within the harbour.
QF actually played a large role in getting MSA up and running with jets, for both ground crew, flight crew, and paperwork/procedures.
Yes, I'm sure they did but I think it was BOAC that got them up and running with the Comets, possibly the initial B707s too.
