The supersonic jet is thought to have rolled over a titanium strip on take off from Charles de Gaulle airport.
Rather than the titanium strip I prefer the story about the missing spacer on the undercarriage causing the aircraft to diverge from the centre line taking out runways lights which caused the puncture.
Also wasn't there a wind change just prior to take off resulting in a downwind takeoff and then the aircraft being too heavy for the distance available.
