ALL this has been discussed before!! Remember my posts on Oooslem birds!
Even if the crew went IMC, to be negligent it would have to be deliberate and with the aircraft under control. Sqn Ldr Burke, the leading expert of the time, says this "may" not have been the case.
To save you the effort this is what I said recently.
If you read my posts I have always been of the opinion that a verdict of pilot error was much nearer the mark than gross negligence.
and yes to another post - it is quite possible that if they had a problem both heads could have been down in the cockpit etc etc etc.................ad infinitums past.
Believe whom you will - Sqdn Ldr Burke or whoever else has a view.....
