This is the best I can contribute at the moment, folks. I'm looking to see if I can find my dad's old aircraft photos as his are better than mine I'm sure.
Anyway, here we have what looks like an ex-Air Canada DC-8 (could be the same one that's in Liffy 1M's photo in post #23), a ZAS Boeing 707, an ex-BA Trident and a Channel Express Herald. I'm thinking this is about 1984 or 1985.
