just a few thoughts
Before you regular posters attack me I want to point out I am a professional pilot but of the 737 classic? variety and have never flown any MD varient.
Once again, I refer to post 376.
It may well be a hoax (the poster never claimed it as his own) but it may also be genuine.
Many accounts say that the aircraft was veering to the right at an early stage. In the event of reduced but symmetrical thrust this would not happen until the stall.
I find it difficult to believe that an experienced pilot would not be able to control an engine failure, particularly in an aircraft with the engines so close to the centreline. I do take on board the points about atmospheric conditions and the possible discrepancy regarding pax weights.
In the SIM I have seen a heavy 737 get airborne with less than normal takeoff thrust get airborne at far less than normal speeds. eg Vlof <100kts.
Engines fail very rarely. The aircraft veered to the right.
In my opinion the rto will prove to be a red herring, although it is worth remebering that MEL items assume no other failures or combinations of failures.
It is only my opinion but I think an unlocked reverser is looking likely.
once again, just my own opinions
