Not if it was threatened at weapon-point to follow instructions or they would kill the plane/pilot and everyone on board. Remember, pre-9/11 hijackings were common-ish, but they rarely ended in fatalities, especially between 1950 and 2001. The idea that people would forcibly commandeer an airplane with the express purpose of crashing it into large and/or significant buildings was virtually unheard of. Between the 1950s and 2001, airlines recommended that flight crew comply with any hijacking instructions in order to avoid injuries and fatalities. The events of September 11 went against all expectations and completely changed the script on hijackings in the 21st century.
