The mechanical force is via the wind velocity and direction. Wind velocity of greater than 20 knots with higher gusts, especially flowing over rough terrain, can lead to an unwelcome flight. I looked at the airspeed and it was jumping +/-5-10 knots. Ah, a wind shear and a lot worse was going to mess with our landing.
