I believe so.
The killer was that the "all flying" tailplane was servo tab controlled ( a bit like the Britannia's ailerons) i.e. the pilot had no direct link to the flying surface which basically just flew in the breeze. Lithgow went through a series of actions which he calmly recorded. These included applying max power, frustrated by the rate of descent causing the intakes to be stalled. There were a number of my Father's associates on board.
BAC sent a team across to tbe USA to explain to such as Douglas what went wrong.
