Alex Whittingham:
You don't seem to understand that the DC-10 crew were not taught an incorrect technique. 27 years ago it was considered to be the correct technique and it is only with your first class honours degree in 20/20 hindsight that you are able to say now that it was an incorrect technique.
The training given to the crew concerned was approved by the FAA, the CAA and God knows how many other national authorities.
I would guess that you have as many hours on the DC-10 as I have on the Handley Page 42 so let me assure you that whether they had V2 or V2+20 did not affect the outcome - it only speeded up the inevitable. This was confirmed to me by a McDonnell Douglas DC-10 test pilot but then, what the hell would he know?
