excellent post - thank you Spitfire!
two comments in relation that you all might find interesting:
1) you might notice just how much the flight-crew bounce around when taxiing - one of Concorde's unique 'features'! i used to speak with Concorde crews on a daily basis, and they all said that it was something that many of them never got used to - in fact some even felt sick because of it!
because Concorde's nose leg was SO far back, and that the fuselage was so narrow, the flightdeck would sometimes bounce up and down by as much as 2 feet when taxiing on uneven taxy-ways! in fact Concorde avoided certain airports because of this - the worst i believe was Athens, where it was all but impossible to operate because the crew would get bounced around so much!
2) Concorde's ability to 'supercruise' without reheat - it's unique feature, as the Captain said. it was this factor that the Russians never solved with their Tu-144, which could only maintain M1+ with reheat.
contrary to popular belief, this has very little to do with the performance of the engines - it's all to do with the ingenious intake ramp system, to which the Captain referred. this was the main purpose of prototype 002, now retired at Yeovilton - she spent six years developing the computers that control the intakes. the fact that the Olympus engines could maintain M2+ by taking in sub-sonic air seems like witchcraft to me!
lastly, as an interesting bit of trivia - those same computers developed on 002 were removed and held under lock and key, by BA/AF engineers when each service-aircraft was retired. why?
because they are still on the official secrets list!
