I remember Air Ecosse with some affection from my time at EGPF....indeed, my last performance as an approach controller was to give an SRA to a "Hairy Socks" Bandeirante.
At one time I believe their were more than 20 E110s on the UK register. One night at Glasgow we managed to attract 15 of them, most of which seemed to be mail flights. A resident of Bearsden phoned up to complain that we seemed to be doing training in the middle of the night because he thought he`d seen the same aircraft pass over his house repeatedly.
