BOAC,
do you mean the address at the MoD?
If so, its:
The Assistant Director (Secretariat & Lower Airspace)
Directorate of Air Staff
Ministry of Defence
Main Building
Level 5, Zone H
Whitehall
London SW1A 2HB
You are absolutely correct in saying that no one has conclusive proof as to what actually caused the accident. That has been the main thrust of the campaign for the past ten years!
If it needs another ten, then so be it!
Hopefully not, though.
My best, as always.
