September 11th, 2001 was a huge event which affected the morale of many people. People were scared, outraged, confused, and overall at a loss for explanation over what happened in New York City, Washington and in Pennsylvania. The idea that people could first, smuggle knives on board the planes, second take control of a jet liner and third crash it and kill thousands of people shook travelers’ trust in the airliner industry. People were afraid to travel by plane and became critical of the security system at airports. Nowadays, the problem has turned a new head as travelers criticize the extremity that involves the security at airports and aboard the planes. The customers complain of not being able to bring liquid on board, being patted down too often before being let on the plane and an overall extreme means of searching for dangerous weapons.
