You will find this hard to believe but I saw a captain (from some place just north of Australia), take off from brakes release in the simulator with flaps up ignoring the takeoff warning horn all the way down the runway. The F/O just sat and watched impassively.
The F/O forgot to call rotate so the captain simply did not rotate which saved him from stalling. At 170 knots the aircraft was still boring down the runway horn blaring until the F/O said 'Sorry - Rotate" at 180 knots. The captain got away with it. If in fact this is what happened with the Mandala Airlines accident, then I can believe it. The lack of action by the F/O is a culture thing.
It is quite frightening to see these sort of chaps in command of 737's.
