patrickal,
Your comment,
"I still do not understand the departure of both engines so quickly either during the rudder deflections or immediately after the departure of the fin."
The 27' vertical stabilizer becomes an additional flight control surface in the presence of rotating vortices. The rotating vortices striking this large surface area, broadside, initiated an instantaneous left yaw! The extreme inertia forces, created by this abrupt yaw, tore off both engines from their pylons and the tail from its attachment Lugs. The abrupt left yaw also caused an immediate, left, Dutch Roll.
This was the first such accident in 100 years of flight.
