Could you humour me and tell me the sources you're quoting there?
the BEA, in a confidential note
The source is the Concorde trial notes
For the video .. the source is obvious
All this merely shows that the BEA sometimes exercise intellectual dishonesty .. no more .. no less
BEA (in the video) cites reasons for ground the Concorde
BEA cited the same reasons long before in a confidential memo .. but had not decided to ground the Concorde (why confidential .. and why not make a recommendation for ground the Concorde ? )
The BEA's note in 1979 shows that the accident was foreseeable ... but in fact (in 2000) .. it's show to the public that Gonesse accident is a surprise .. it was not foreseeable (they discovered the reasons by primary investigations after the crash) .. nobody could imagine that .. etc. ..
