Had a school trip to Cosford Aerospace Museum in about 1979 (roughly). On arrival an RAF type, seemingly oblivious to any stereotypes, and with a handlebar moustache greeted us with the phrase 'come this way, we've a bit of a flap on', and shepherded us outside to witness the arrival of VC10 G-ARVM on its last flight. It did a go-around to assess things, and then skimmed over the trees near the threshold to do a full stop landing towards the railway embankment. Not sure of the dimensions involved, but we were told that it was the shortest runway a VC10 had ever landed on, and (memory is a bit more hazy about this) it was the VC10 chief pilot's last flight. Impressive sight.
