Dear Roy,
Certain factors are indeed very pertinent to this event.
The blame game is very easy to play, and same might be very convenient to some. However, they are not to those who died and their Families... and it is they who are far more important in all else in this matter.
All I can and will say is that the proof of liability is extant. The cause is more difficult to prove, but all is dependent on how much smoke is blown over the matter... and, of which, there is a great deal of the latter.
May I sum up by saying, that, Concord was - and is still - a great aircraft, one indeed, that remains in mahy areas advanced even now. A friend was a mfg. hydraulics engineer on her/the planes and flew on numerous test flights, and, whilst there might have been 'tweaks' required along the way, there was nothing that should have prevented these planes from flying... apart from.............
Maybe the French should have paid better attention to their airports (one did actually fall down), maybe Air Port Mgt. should have been better (we all know it could be), maybe better attention could/should have been paid to runway Maint..
And so it goes on! The responsibility is there for all to see?
Regards, Bernard
