We are of course going round in circles and time to call a halt. Nothing in life is absolutely certain we must judge from evidence, experience and perhaps having been there. The house of Lords, sundry politicians, lawyers etc do not meet the above. If you wish to argue your case on lack of absolute evidence and a rule book fine, you may get a technical dismissal. Your argument that this incdent was caused by a technical malfunction is tenuous in the extreme as witnessed by the range of straws grasped. Perhaps summed up by the ludicrous idea that the crew were trying to select an emergency squark as proposed by the proposterous ch 4 documentary.
