Sky News reporting that decompression has been ruled out. Not that I trust Sky but they have reported this in news at 10. No qualification i.e. explosive or slow decompression. Suggestig it has been ruled it out as a whole.
Probably because it was the head of BEA who said it was ruled out when he gave a press conference this afternoon.
He also said that it appeared the plane was in a controlled flight until the very end to quickly add that no pilot in his right mind would fly into mountains and that the AP could also do that.
