It has to be the VC10 - no contest.
Grace, pace and a descent amount of space. Designed in the days when style was style - what other airliner has a 3 space urinal fitted at the back??????
Ok, so it's noisy but where else will you get 8000'/min SUSTAINED ROC out of an airliner (yes I did that - out of Oslo Gardermoen - and we didn't bust any rules, either).
