First off, the autopilot does not store routes. That's done by the Flight Management Computer. The autopilot can take inputs from the FMC. But yes, you can store routes there. But what would be the point? You can punch in a new route by hand in a few minutes.
ah okay, yeah the FMC, that's what i meant to say . Thanks for the clarification . Why i asked is that the turn was pretty sharp; almost instantaneous, after that handoff...so maybe the route was ready to go instead of someone taking the time to input the routes. I mean whoever did it, has to know what the waypoints are, what airway it is, where it goes, etc, etc....this really seems to me that it was either one of the two up front or somebody on the manifest that has flight experience.
You wouldn't need to use the FMC at first. Just enter a new heading in the Master Control Panel and switch from LNAV to Heading mode. Once on the new heading, enter the new route on the FMC, then switch back to LNAV. It's not really rocket science but you'd need a working knowledge of the autoflight system.

Service ceiling is 43,100 feet, according to several sources.
43,100 feet is still not 45,000 feet.
The service ceiling can be limited by different factors. On large airliners, it is typically based on minimum time for emergency descent, not on aerodynamic factors like stall buffet boundary. Plus there is a safety margin for either limitation.
In an case at the service ceiling, the airliner can by regulation still climb at a minimum of 100ft/minute, so by implication it can in practice go higher.
In other words, a 777 at light weights can probably go well higher than 43100 feet before reaching the absolute (aerodynamic) ceiling. How high would depend on weight and aerodynamic factors.

What is the duration of recording capacity for the cockpit. NBC Nightly News I just watched mentioned two hours, but that seems wrong.
Sounds about right for voice recording, though I think the regulatory minimum is lower. Flight data would be longer. At least 25 hours if memory serves.[Edited 2014-03-14 19:31:57]
