My understanding is that aerodynamic modelling and simulator runs have shown that a committed decision to push nose-down, regain airspeed and recover from the stall, could have been successfully initiated all the way down to 5000 feet. The Captain had another 2mins 15secs (approximately) before reaching that level, and another 30 secs before impact after that.

There was time, if only someone had said the word ‘stall’ out loud.
