The vortex is a horizontal tornado with 200plus mph wind velocities. We know what damages tornados can do on the ground, right.!
Right, but houses on the ground don't move.
The airplane was travelling at more or less the same speed.
If you consider the vector diagram which compounds the forward velocity of the aircraft with the sideways velocity of the "tornado", you will immediately see the difference of the resultant velocity: the resultant vector will be set at an angle of at least 45 degrees, thus much less powerful.
No evidence the pilot used right rudder input to counter the steep left bank, along with his full right aileron control input. If the pilot had had rudder control, he may have been able to recover the aircraft.!!!
Maybe, just maybe, the wild reaction severed the tail
before developing the steep bank.
