I watched a show on TLC about a plane that crashed.
There was a NZ couple who's son was aboard the plane and got sucked out of the plane and died. I don't think they ever found his remains.
The couple basicaly went on a 4 year long journy to find the cause of this. It turns out there was a faulty connection on the cargo door and it would automaticaly come open during flight. It was also something very simple to fix. But the company refused to fix it for several years. The couple faught and faught and got no where.
Finaly after several years of fighting a plane was sitting on the tarmac in front of everyone and the door just popped oepn for no reason and the FIA people saw.
The moral of the story is, companies are jackasses. They will let nothing stand in their way of a profit. The airline company figured the 200 lives every 4 years was negligable compared to the millions of dollars they would lose in down time to fix their planes.
But this is also why you need to speak up. Because if you don't, who will?
