Few planes get better-looking as they get modified, but the MR3 was the nicest, I think - the tricycle undercarriage really suited it.
There was a better video using a lot of that footage, but it's gone 'private' now, for some reason.
A lot of aircraft were quite recognisable from their sound, but the Shackleton was unmistakeable. The Argosy was another, no mistaking that, either.
