Are you serious???
Has anyone here ever flown the 747???? Brake problems??? Thrust Reversers???? First of all the FO and the FE should be immediately exonerated, given a raise and be put back on line as by the time they could have noticed what the other guy did it would have been too late. Several thousand feet of runway exists after taxi way B thus probably a high speed exit on a high speed taxi way. All it takes is the flip of one commonly used switch at just a little bit to high of speed and that airplane is going the opposite direction it was being steered toward. It sure would be convenient if it were a brake/reverser problem, but I sure hope that these two fellows are not being punished because an arrogant Captain cant admit to his own mistake.
