Hijacker finally agreed to having steps raised. (It is noted Boeing 727 aircraft unable to take off with stairs in lowered position. However in order for stairs to be lowered in flight, it is necessary that rear pressured door be in open position on take-off.)

United Air Lines hijacker ordered stewardess to go to front section of plane and did not require instructions as to how to operate lowering mechanism of rear stairs.

In United Air Lines case, plane crew was on oxygen flying at 16,000 feet for a period of one and one-half hours prior to hijacker jumping due to open rear stairs.
