I thought maybe Capital as well, but unfortunately they went bust in 1990 apparently, and I didn’t join that business until mid 90,s, so unless Wiki wrong then Capital ruled out.
However Capital was formed from Brown Air who I flew to Oslo with from LBA a number of times in 1984 I think, and that was a quite unique carrier, more 633 Squadron than an airline, but great fun with very happy crew. Still no idea re Short carrier though.
