who said the concorde was a flop it has generated more money than any other airliner in the world. The only reason it was discontinued was because of the cost of fuel. They should not have the same problem with hyprsonic buisness jets.

Still an impressive structure nonetheless. The fact that the towers were designed with a 707 in mind, The 767 was full of fuel, traving alot faster and weighted alot more than the 707. The towers stayed up long enough to allow thousads to escape. I saw an interview with the architect, he looks like he will be haunted to the end with the collapse of the towers. Really there was nothing he could have done to predict this or counter it.
One has to wonder, is it practical to design a building to survive a strike from a 500000 lb object traveling at 500 knots? The Towers came close. It was really the fire that doomed them, not the actuall strike in any case
