Why did BA and AF line the fuel tanks with Kevlar? I mean surely a piece of tyre striking the fuel tank of ANY aircraft would cause the tank to rupture. It was just unfortunate that Concorde, such a high profile aircraft, was the next in line for T/O after the Continental A/C which apparently shed the metal. The same thing would have happened if it was a 737. Would all 73 operaters in the world then ground their fleet of 73's then line the fuel tanks with Kevlar? nah I don't think they would. IMHO it was just a case of Concorde being in the wrong place at the wrong time.
