Wing drop during stall
What is the reason that there is a possiblity of a wing drop during a stall?
I can only think of 1 reason:
Left & right wings are not 100% same (though in theory they are supposed to be designed that way, but nothing is perfect), and also the airflow at left & right wing might not be the same due to sideslip or wind or some other force of nature, therefore the wings might stall at slightly different time.
Do I score at least 90%?
