Sadly (or happily), I'm old enough to remember pre-extension jet movements like the one-off Monarch 757, Transavia Caravelles doing the "Bulbfields" Flights to Rotterdam in the spring and the occasional vists of British Midland 1-11 500s. I can also recall the clouds of red dust being generated by Britannia, Orion and Dan-Air 737s as they accelerated away down the then Runway 15, whilst the runway extension work was taking place.
You can also add to your list Air Transat Tri-Stars and the Corsair, United Arab Emirates (SP) and Air Hong Kong 747s, although the latter was a one-off crew training visit. I submitted many of my photographs some time ago time to LBAviation and someone has put together this collection taken from there on Youtube. Please see the link below. About 40%-50% are my photos. Not sure who took the rest. I witnessed the British Airtours Tri-Star going off the end of 14 and the photos are also on the link!
