From page 5: "the standby musses transfer to batter power if normal AC power is lost"
I think this is what the CNN guy was talking about. This sounds like a battery system just for the fly-by-wire cockpit systems, not for the whole aircraft. He said it was good for about an hour.
For my scenario to be correct, there had to have been a problem that knocked out the power from the two engines, the APU, and probably from the ram turbine as well. That is obviously a very bad situation, and could have been an explosion, but one that didn't bring the craft down immediately.
There was a case a few years back where pilots lost almost all controls for their 747. I think all they had was a throttle control for each engine. By adjusting the relative power to the engines, they were able to control direction and altitude for awhile -- a half hour as I recall. But I think that did end up crashing. The point is that these were very, very experienced pilots and they might have been able to fly a badly damaged aircraft for an hour.

Yep... someone from Boeing should be able to verify if it was from the plane or not

If you have a decompression that occurs at 35,000 feet, you might have as little as 8 or 9

If this is the scenario, then the aircraft must be on the bottom of the strait

My theory above is based on the reporting that the craft was seen to have doubled back

But if it is so close, the airport should have been able to pick up the plane on radar
