I must be blind, I could not see any ref to M2 or M3 or 84k ft in the links. I did fly out of Embakasi (Niarobi) in 1965 in one. then back from Changi in 1970. Did the Washington Saturday run several times in the 80s. recall people saying we were overtaking 747s. Miss BOAC 1954 was the senior steward or what ever they called them at the time. Was Concorde banned from IAD due to noise. My mate who lived at Fairfax Va always new when we had arrived so had the steak in the smoker for when we had cleared customs. VC10 was the noisiest thing flying into IAD at the time. Very strong aircraft. I did some design work on the Super tankers when it was found they had extruded stringers. the assumption had been they were the same bent tin as the standard. The original RAF ones had a wet fin. I went down to Weybridge just before the design office moved to Chadderton (may have been Woodford for a while). I miss those days - rose coloured specs!
