Introduction The famous terrorist attack on the Twin Towers on September 11 of the year 2001 in the US was a key event that heighted the security awareness concerning the susceptibility of the transport modes especially the air travel. As a result, airport security came out as a very significant aspect of the overall discussion of global security as specifically the US homeland security. Millions of cargos reach various places through aircrafts every day. Without air travel, the world might come to a halt. The aviation security addresses all the potential threats like unlawful acts affecting civil air transport. The September 11 attacks resulted to a huge loss in all aspects: loss of lives, crushed economy and transportation threat. This paper offers a perspective of the formation of the transport Security Administration (TSA), as well as its impact on Air travel. It also highlights the evolution of TSA in conjunction with the laws that empower it to function effectively. Evolution and Impact Air Security before TSA Before the formation of TSA, private security contractors were the only managers of air travel security. The performance of these contractors was doubtable long before the 9/11 attack, which saw 19 hijackers get on board with knives and box cutters seizing control of the plane to cause the fateful tragedy. In only two months, TSA came into being to allow the government to have more oversight on national security after the incidence (U.S. General Accounting Office 3). The federal government also listed all the items that were henceforth not worth carrying with planes. Before then, the private security contractors would bid on the security jobs at airports and then conduct the screening to detect threats once given the job. In 1980s, these private contractors introduced dogs because of increased drug trafficking. This heightened the war on drugs. However, the private security systems had many loopholes. For instance, they were to make a 100% check of cargo on passenger planes according to the US policy (U.S. General Accounting Office 3). The belly cargo on the same plane, however, did not undergo major screening. Before the famous 9/11 incidence, the United States of America had a relaxed and reckless security process. The security personnel only relied on simple means of questioning and looking for security threats. The ticket agents would only ask the passengers for the tickets. They would interrogate whether the passenger packed the bag him/herself or whether the passenger had obtained any item form a stranger or not (U.S. General Accounting Office 3). After that, the passenger would go through the metal detector machine after emptying their pockets. They placed keys, coins, pens and probably a pocketknife on a tray, which goes through the screening machine. Simply put, the main tools for security detection were X-ray machines and metal detectors for domestic flights. Only the international flights luggage was x-rayed. Otherwise, the rest of the luggage once inspected was not to go through the X-ray machines (U.S. General Accounting Office 3). In addition, meals served on the planes had a metal dinner knife accompanying them. However, the terrorist attack on the Twin Towers was a shock, exposing the security loopholes in the then existing syst
