Boeing occasionally demonstrated the 727 to prospects by taking off and
setting one engine to idle just before rotation. You might want to write to
them and tell them that they were full of it, too.

This is called a V1 cut and it is done on every sim check on every
crew for every plane flown in the world. The regs require the planes
weight to be limited so the plane can either stop on the remaining
runway if the engine fails before V1 or continue (and climout) if the
engine fails after V1. Go back and read Moores exellent post on the
subject.
