As I said earlier, Continental didn't directly attack Concorde's airworthiness, which would have required attacking AF, BEA, Aeroports de Paris, etc., probably because their seasoned lead lawyer reckoned they stood less chance of success with that approach than the one they took
I see generally what you mean , but in what way could the BEA and ADP be held in any way responsible for Concorde's airworthiness?
The owner/operator perhaps.
The builder perhaps.
But holding the agency responsible to investigate accidents on their turf as being implicated seems a little far fetched.
Some believe that ADP were slack in not inspecting the runway after each TO.
Imagine screeching condemnations of delays at CDG if a runway inspection took place between each TO.
