The concorde crash was as crash:
-) of a French built plane
-) flown by French pilots for a French airline
-) in France
The UK felt they were also involved because they helped built the concorde, but the French made it clear right from the first day that any British inspectors would be allowed on a courtesy basis only and that their eventual findings would not constitute part of the official report without their agreement.
If an American Airlines Boeing 757 would crash in Miami, I don't suppose the British would want to co-write the official report, would they?
The final conclusion of the BEA report is cristal clear and 100% correct to me:
the doomed Air France Concorde was operated and flown according to normal day to day SOP's as common to Air France's SST fleet.
The principal reason leading to the dramatic events in CDG was the presence of debris on the rake-off rwy, which was traced back as uncertified parts belonging to a Continental Airlines DC-10 taking of only shortly before the Concorde.
All the rest is pure speculation and do not belong in an aviation accident report.
