I found a very interesting show Sunday evening right before the Oscars. It was shown on NBC Dateline. It was a report about the Air France Concorde crash almost 10 years ago. It had great animations of the possible causes. Several witnesses claim they saw the fire coming from engine 2 even before the tire was cut flying over that metal piece left on the runway. One witness believes that the fire originated from engine 2 itself and not from the fuel tank being sliced-open. The reporter says that Air France plans to sue Continental Airlines for negligence. Also brought out was that the spacer between the tires was missing. As a result, the tire wobbled during take-off which could have contributed to the fire.
