I was a member of the BOI into this accident, all those years ago. Whilst I can't remember the names of the 2 pilots, the OCU istructor was a Flt Lt of huge flying experience, the student a Squadron Leader. There was NOTHING wrong with either engine (they were extensively tested by Rolls Royce). What happened was that the instructor, without checking his instruments, decided instinctively (but almost certainly mistakenly) that the a/c wasn't climbing, seized control and banged it back onto the runway - with far too little remaining tarmac. It's also true that the a/c narrowly missed a woman pushing a pram on the road. The president decided that we didn't have enough evidence to reach a firm conclusion as to the cause, though we all felt it was finger trouble on the flight deck.
