When I was in the Boeing 777 simulator a few weeks ago at the Delta flight training center, I thought I saw the masks attached to the side and slightly to the rear of the seat. I am sure they practice decompression and donning the mask on a routine basis.
According to the manufacturers of the black boxes who were interviewed yesterday, the "ping per second" will last 30-days on its battery power and operate to a depth of 20,000 feet under water. I do not know if their flight path at loss of signal was over the water with the bottom at that depth or deeper, but its interesting to note the maximum depth for the "ping", which would be picked up with passive sonar.
