For a while during the early 1980's Dan Air used Twin Otters I think the flights started in Bournemouth, I did the BHX-MAN-NCL sector a few times, indeed there was a period when you had to change a/c in MAN, with the northbound service originating in ABZ, the a/c arrived together at MAN and you had to go into the terminal and walk back out again. I remember one trip when I passed Dennis Waterman and Rula Lenska as we changed a/c. The Co-pilot used to hand round coffee in a flask and biscuits! Happy Days sitting watching the flight deck!
