An AirAsia plane that crashed last month with 162 people on board was climbing at an abnormally high rate, then plunged and suddenly disappeared from radar, Indonesia's transport minister says.
What I meant to say is that it sounds like a classic "get caught in a storm because you really want to get home"
They have flight plans and paths that need to be followed, which they were on. They climbed rapidly and more rapid than the aircraft should be allowed to do under normal circumstances. The article refers to the Air France crash which did the same thing, rapid climb till the aircraft stalled. Because of faulty information the aircraft could not recover and it crashed in the ocean. My bet is that something similar to the Air France crash where temporary inconsistency between the measured speeds, likely as a result of the obstruction of the pitot tubes by ice crystals, causing autopilot disconnection and reconfiguration to alternate law. Which then led to a number of bad choices. Because they were flying at night and in bad weather there are no visual reference indicators like the horizon, sun or even stars.
Siswosuwarno said that the weather satellite images at the time showed a formation of storm clouds reaching up to 44,000 feet (about 13 kilometres). He added that flight data showed that the jet was in a dangerously fast climb and stalled before going down slowly into the last position of 24,000 feet (about 7 kilometres) high recorded on the radar.
He said investigators were still looking into whether turbulence or updrafts contributed to the plane’s drastic climb as repeated stall warnings were heard clearly on the cockpit recording within four minutes until the end of the recording since the plane reached more than 8 degrees of its pitch angle.
"Jabberwalker" said ... another fly-by-wire Scarebus nightmare. Maybe, some defective instrument told them they were descending rapidly, they pull back, stall, etc.
If they really did pull up like a fighter aircraft, excessive wing loading may have folded them up, and they drop like a stone.

Shouldn't they have been able to feel that they weren't in a freefall regardless of what the instruments indicated?

Boy, can I relate ot that.

Fly by wire has nothing to do with a stall.
It does if the sensors are giving false readings and the computer is flying the plane according to them.
It appears you have no understanding of the term fly by wire.
That's okay. The Flight Reorder will tell the whole story.
