The only other one around that time would have been a Laker Airways one I have seen large photos of them in the airport. The later Dock strike produced the Merchantman and CL 44 shuttle every space rammed with a box of fags. Gulf Wars and Balkan war provided many wide body aircraft with weekly 747, DC10 or Airbus. And an Antonov 124 with some urgent tank spares.
Most planes you can think of have been in so the airport can handle them, hopefully the management team will be good enough to go and get them without being hindered from outside interference. We have one of the largest army camps in Europe just down the road.
