Yes,it does. The problem is that the pilots didn't know that they were in stall because of conflicting readings from their instrumentation due to a failure in the pitot-static system. Pitot-static runs airspeed/altimeter/vertical speed indicator.
Doesn't get much more wrong than that, poor guys. Is there some kind of G/inertia meter that could have clued them up? To see an overspeed + climb but the freefall indicator is going crazy.
The VSI (vertical speed indicator) is the "freefall indicator" of which you speak. :)
The problem is that when there's the pitot-static failure the VSI (generally) indicates by "sticking" wherever it was when the failure occurred.
"Speed" means a different thing to a pilot than it does to a non-pilot. Groundspeed is irrelevant (aerodynamically), airspeed is everything. To sense "overspeed" you have to know airspeed. And since airspeed is a measure of the movement of the aircraft relative to the medium it's moving through (air), there has to be a system to measure that movement. That system is the pitot-static system. The pitot tube sticks into the uninterrupted airflow, usually on the wing somewhere, the static port sits where the air is calm, usually on the fuselage. The airspeed indicator in particular relies on the differential between the two inputs to determine airspeed.
