Isoroku Yamamoto

In the first six to twelve months of a war with the United States and Great Britain I will run wild and win victory upon victory. But then, if the war continues after that, I have no expectation of success.

There is only so much negotiating and maneuvering that can be done while the aircraft is under siege in mid-air. Therefore, the best way to put a stop to hijacking is by having high levels of security implemented by qualified and trained personnel both on the ground and in the air.
