Thanks unclenelli.
However as I know B***er all about a/c can I ask you to repeat it in terms I can understand please.
What I would like to know is if the plane exploded at 3,000 feet which is what we were told .Is that 3,000 feet above the ground + 3,300 feet down to sea level. So the atmospheric pressure would be equalivalent to being at 6,300 ft . Yes ????
