The a/c is designed for structural limit load at 1.51 G. Two G buys the farm.
OK. Now what is the explanation for the vertical load pick-up arm between the Rudder and the V/S failing at 36g with up/down shear forces and not radial ones?
IMHO the brick wall was not the 90 degree to line of flight one, but the one vertically below the line of flight, i.e. Terra Oceania. Any deformations to the left and forward of line of flight (at point of impact) are the result of small moments along those vectors that also suddenly accelerated to zero.
