full power in a stall

Hello,

It was low on speed if we thrust the transponder data.

Energy profile suggests not enough power for whatever reason.

Yesterday a witness in the plain confirmed on the dutch news that after the drop (read: stall) full power was given until the crash. Could still be one engine, but power was heard.

If both engines were available pitch control is difficult at low speed due to the very high pitch-up momentum from the engines. Even worse if AP was on and trimmed for low speed.

A low power stall recovery at low altitude is not an easy thing on a 737. Control forces are high. The pith-up momentum of the engines can aggravate the stall condition.

More food for speculation?
