That was me that posted that, and I've been rooting around for information in other places; take it with a grain of salt, but other postings I've seen on other boards indicated that the escorting F-16s may have seen oxygen masks deployed (indicating depressurization) and that either the F-16 pilot, or a passenger--I've heard both versions--reported that the pilot's face was "blue".
It almost certainly wasn't a bomb, because the plane flew along at cruise altitude for some period of time, probably on autopilot, with no visual damage that the escorting fighters could see and no contact with air traffic control, hence the fighters. So Occam's Razor says that it's a pressurization problem (which would also explain the "frozen" bit...it's pretty darn cold up there at 34,000 feet). But pilots are trained in what to do when that happens, and there's two of them up in the front of that 737. And if the cabin pressure alarms go off, the first thing they're supposed to do is put on their own masks...the second is to get the airplane the hell down to 14,000 feet or lower as fast as they safely can. EVERYTHING else is secondary, because at those altitudes, hypoxia will turn anybody into a blithering idiot in mere seconds, and knock them out cold seconds after that.
It may not be terrorism. It may just be a mechanical failure compounded by pilot error. I seriously doubt it was a 9/11-style hijack, or a bomb; if there was foul play involved, my SWAG is that it would have to have been on the maintenance side. But we won't know until the investigators get to the crash and start digging through the wreckage.
All we know for sure right now is that a helluva tragedy just went down.

This is very strange! Blue skin indicates cyanosis - loss of oxygen brought on by a number of factors, many of which occur in flight (e.g. high altitude/cold), but which occur outside the plane, not in the protected cabins. There are also pesticide poisonings which produce blue skin... Could it be they were gassed?
