The British Big Three; Hurri, Spit and Lanc.
Hmmm, the F-15 in LOMAC is nice to fly, and when bits drop off, I can understand the warbling 'Electronic Nagging' ("Right Engine fire, Left Engine fire, ILS Fail, ECM Fail...") and I quite like the A-10, used to see a lot of them when I first moved up to Suffolk as they were based at Bentwaters at the time. I also have a bit of a thing for the MiG-29, probably because it was one of the first planes I kinda knew about back in the late 80s due to a NES game called "MiG-29: Soviet Fighter."
Commercial planes....probably the DC-10, Ju-52, Concorde (of course), DC-3 (An Iconic plane), and well, I dunno if this counts as commercial, but the C-47
Oh, and the Apache and Chinook!
