http://www.dailymail.co.uk/news/arti...ed-museum.html Excellent! Really like the over water shots - including the shadows on water. There is a group in England who have raised some $120 (or Ŗ - not sure which) in order to buy or lease an Air France Concorde which would be used for air shows and perhaps charter flights[1]. A 2nd one would be put on static display - perhaps alongside the 'eye' in London. Among the group's leaders are former BA pilots. BA itself is on the sidelines as all its Concordes have been consigned to museum type roles (leased or lent out). [1] The fateful crash happened to be a charter flight. |

I've been on concorde although not while in flight. I was suprised how small and cramped it was beign more like an old bus than a supersonic jet. I spoke with a man who flew the Concorde several times. He was not very tall, and said that he could not stand up straight in that airplane, as it was small inside. His best memory of his flights: getting a manicure in his seat. Loony design of the century: the Concorde's fuel tanks were purposely situated just beneath the plane's skin, to help cool the skin at supersonic speeds. Using jet fuel as a coolant, in exposure to heat????? That is about as smart as Boeing's use of flammable lithium ion battery packs, to save a mere 60 pounds of weight per airplane. Mort Linder |

Not as looney as the all titanium SR71 which leaked fuel on the ground and until the fuselage skin had heated up in supersonic flight and expanded to seal the tanks. Then it would top up the tanks with mid-air refueling and complete the mission. -- Regards, Savageduck |

Mort Linder I don't know how tall your friend is, but I am 6'2" and don't recall any problem standing up. IIRC the cabin seating was similar to first class in a 727. They let me on the flight deck, (pre-911.) I asked them about that, and the pilot said there was no place to take the plane. The food was pretty good for airline food. -- PeterN |

Irrelevant obfuscation does not change the facts.The thin skin tore from a small metal fragment on the runway, and the exposed fuel tank caught fire, killing everyone on board. I do not care if it had 2 tanks or 22; the stupid design killed people. Mort Linder |

The heat of supersonic flight would have cooked the passengers and crew if there wasn't something to absorb the heat. Using the fuel made sense as the absorbed heat ended up being dumped in the engines and contributing to the thrust. The fuel was used not only to help keep people cool but to maintain the fore and aft trim of the aircraft. The centre of lift changed considerably as the speed increased and literally tons of fuel were pumped backwards and forwards to keep the aircraft in balance. -- Regards, Eric Stevens |

Irrelevant obfuscation does not change the facts.The thin skin tore from a small metal fragment on the runway, and the exposed fuel tank caught fire, killing everyone on board. I do not care if it had 2 tanks or 22; the stupid design killed people. that crash had nothing to do with cooling, the issue you originally brought up. furthermore, the metal fragment did not puncture the fuel tank. it punctured the tire, sending rubber pieces toward the plane, causing a stress fracture *elsewhere* due to the impact. the crash was due to a combination of events, including human error. it was also the *only* crash in concorde's history. http://www.askthepilot.com/untold-concorde-story/ The plane went down not because of any fire, directly, but because 1., it was flying too slowly; 2., it was several tons overweight and beyond its aft center of gravity limit; 3., two of its four engines were damaged or erroneously shut down. .... An investigation by The Observer suggests the truth is much more complicated. In the words of John Hutchinson, a Concorde captain for 15 years, the fire on its own should have been ŗeminently survivable; the pilot should have been able to fly his way out of trouble.˛ The reason why he failed to do so, Hutchinson believes, was a lethal combination of operational error and negligence. This appears to have been a crash with more than one contributing factor, most of which were avoidable. .... Shocking evidence now emerging suggests that the Air France Concorde F-BTSC had not been properly maintained. The airlinešs ground staff had failed to replace a ŗspacer˛ a vital component of the landing gear which keeps the wheels in proper alignment. Although the BEA disputes it, there is compelling evidence that it was the missing spacer which may have caused the plane to skew to the left, so forcing Marty to leave the ground too early. At the same time, the plane was operating outside its legally certified limits. When it stood at the end of the runway, ready to roll, it was more than six tonnes over its approved maximum takeoff weight for the given conditions, with its centre of gravity pushed dangerously far to the rear. Even before the blowout, Marty was already pushing the envelope. .... The BEAšs critics say that once the tyre burst, the load on the three remaining tyres became uneven, and even if the wheels had been more or less straight before, they now twisted disastrously to the side. The smoking gun is a remarkable series of photographs in the BEAšs own preliminary report. They show unmistakably the skid marks of four tyres, heading off the runway on to its concrete shoulder, almost reaching the rough grass beyond. .... A planešs centre of gravity is expressed as a percentage: so many per cent fore or aft. Brian Trubshaw and John Cochrane, Concordešs two test pilots when the aircraft was being developed in the early 1970s, set the aft operating limit at 54 per cent beyond that, they found, it risked becoming uncontrollable, likely to rear up backwards and crash, exactly as Flight 4590 did in its final moments over Gonesse. The doomed planešs centre of gravity went beyond 54 per cent. The BEA states a figure of 54.2 per cent. A senior industry source, who cannot be named for contractual reasons, says the true figure may have been worse: with the extra fuel and bags, it may have been up to 54.6 per cent. And as the fuel gushed from the hole in the forward tank, the centre of gravity moved still further back. When the plane was just 25 feet off the ground, Gilles Jardinaud, the flight engineer, shut down the ailing number two engine. Both French and British pilots say it was another disastrous mistake, which breached all set procedures. The engine itself was not on fire, and as the tank emptied and the fire burnt itself out, it would probably have recovered. The fixed drill for shutting down an engine requires the crew to wait until the flight is stable at 400 feet, and to do so then only on a set of commands from the captain. |
