Nevertheless, at the point of departure from controlled flight, the aircraft, for whatever reason, experienced a dramatic loss of lift, which is essentially what people mean when they talk about stalling. That this was ultimately due to high alpha, high drag, low power or any combination of the three is not really important.
You are right that isn't important as far as the result goes.
But speaking from a strict definition point of view, I would say that a stall is caused by an exceedance of the angle of attack. Is a wing that is not producing lift stalled? If so is a parked aircraft stalled?
Perhaps, not to clutter up the topic, further posts on this issue should be in
Vortex bursting or another new thread in Tech log?
