1. It seems that the pilots stick shaker began at the same time the plane lifted off the ground.

Almost right before lift off. It also looks like close to when the left air speed sensor started to show up and just after the movements (not angle as 20 degrees off) of the left & right AOA sensors start to sync up better.

Prior to acceleration for lift off the Left & right AOA sensor were not just off in degrees but moving differently. Not sure if initial movement was starting to taxi or initializing systems, but at first left shifts more positive while right shifts more negative (nose pitches up at same time) then after flaps deployed the left starts drifting about 10 degrees more positive while right stays same. With start of acceleration and an initial negative force on control column (I guess to keep nose down initially when speeding up for take off) the left and right AOA move in opposite directions (left decreases & right increases angle). As their changes begin to sync better, the left air speed shows up, the stick shaker begins, and then lift off occurs.

Would the Ethiopia flight coming from airport at much higher altitude have used longer run way to gain speed and then use flaps less?
