We know that the airports are not protected as they should be protected. The terminals are public areas, wide open - anyone can go and walk at any terminal he wants.

After Lockerbie, everyone thought, now we've learned the lesson of how to be proactive instead of being reactive. Unfortunately, September 11 came and we know the result. Thousands of people lost their lives. Security totally failed, not at one airport, at three different airports around the country.

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.

As the head of security for an airline, I can't ask my passengers to risk their lives and jump on a terrorist. This is why we need air marshals on every flight.
