The Twin engine design has evolved into larger aircraft with more powerful engines.
A 27 foot vertical stabilizer, on this aircraft, was required to counter the "Yaw" in an "engine out on take off procedure".
The rotational forces in an aircraft wake vortex can reach 300'/second! (NASA)
These forces striking the vertical stabilizer broadside created an instantaneous YAW which induced an abruprt "Dutch Roll" into the ground! (Low altitude)
The tremendous inertia force, developed by the instantaneous yaw, sheared off both engines and tossed the right engine to the left of course and the left engine to the right of course!
The recorded alternating wind shear forces, a final force of 0.8G striking the vertical stabilizer tore the stabilizer from the support lugs.
AA 587 made a perfect formation join up on the center of a virtual horizontal tornado!
This is the first accident, of this type, in 100 years oif flight!
AA 587 was released for take off, 15 seconds early! Obviously four miles separation is not adequate behind a Boeing 747 "Heavy".
