737 MAX CRASH

If the angle of attack sensor is not right all kinds of things can happen.
Looks like a little wing thing on the side of the plane and moves up and down depending on the air stream in relation to the plane's angle.
I've never worked on that plane and have been out of it for years now.
But there should be two.
One on each side for redundancy.
What systems they feed, IDK.
Probably captains on the left and FO's on the right.
