Firstly let me start this thread by saying how deeply i feel for the familes of the people lost in this! i think i can safely now say that! Its so horrible to come to terms with a loss so great as this!
it was in VERY deep water which is making things hard but i wish the rescue services the very best of luck with this colossal task.
Not been horrible but by accident i found this painfull reminder & to be honest im dissgusted on how the remains of the Lockerbie plane are just Dumped in a scrapyard.? if they is any need for further evidence the weathered remains wont hold any also its most certainly not nice for the familys that lost people
Think it's recorded on a metal strip for maximum fortitude. If water is allowed into the box then the pressure will be equalised and crushing avoided. The recording mechanism will have done it's work and is expendable.
I read somewhere the boxes can survive up to 12,000 ft water pressure. Depending on where they lie they might or might not survive. Also it seems there is a 30 day limit on locating signal transmission which makes their early discovery very necessary. After that, the chances of finding the boxes are very slim.
