A mid-air explosion would show significant deceleration and rapid descent. We don’t see that here. That, plus the lack of communication with the flight crew, makes it more likely that the flight crew was somehow physically incapacitated. The autopilot tripped off, and then the plane slowly descended into the mountain.

It makes you wonder this: was there a possible cabin depressurization that incapacitated the flight crew, similar to what happened the private jet that carried Payne Stewart in 1999 and a 737-300 belonging to Helios Airways in 2005? And the depressurization happened so fast the crew had no time to react?

Yes, but that plane crashed when it ran out of fuel, this plane did not. Also, the autopilot would have kept the plane on course which is not consistent with the decrease in altitude and the crash into the mountain.
