The 9/11 attacks that led to massive loss of lives (killing about 3000 people) in the United States is still disturbing. The Government has introduced new agencies to improve the security, and the citizens’ mindsets have changed. Before the September 11 incident, the security system in the airport was simple. There was a simple metal detector designed for thwarting hijackers with guns (Seaney, 2011). The following are security changes that have taken place ever since the 9/11 incident.
Increased surveillance
The terrorists behind 9/11 attacks had stayed in the United States for a considerable period (Stahn, 2002). According to Seaney (2011), before the incident, some of the civilians noticed suspicious fellows in the airport. This reality has triggered the desire to keep a close monitoring of visitors in the United States. The security even examines international students who arrive in the U.S. to minimize the possibility of living with militia groups in the United States. United Security in collaboration with airport authorities exploits technologies to detect, gather and analyze relevant information on individuals of suspicious actions. This policy is employed by the homeland security to identify and thwart criminal activities before they occur.
Closer monitoring of points of entry
As commodities and passengers enter the U.S. on a daily basis, the terrorist could come on the United States’ soil and move illegal weapon in the United States.

However, after the 9/11 incident, the procedures for acquiring Visas in the United States have tightened (Dillon & Thomas, 2014). Scrutinizes of foreign visitors have intensified at passport control. The airport security crosschecks visitors if they match any of the different profiles, which are worrying about the US national security. The airport monitors every cargo closely with the suspicion that weapons of mass destructions may enter United States as commercial goods (Stahn, 2002). The challenge of this security measure is associated with increased trade in the United States. The idea employed has a plan for preventing entry of terrorist’s arms in the United States.
Remote controlled Airliners
Boeing has developed an alien technology for flying an airliner. Engineering giants in the United States such as Siemens are also working on the technology to avert future terrorist occurrences like the 9/11 (Rex C. Curry, 2014).
Bio-monitors
The United States security department has developed methods that would hinder attackers from boarding an airplane. United States airports are already equipped with Explosive Trace Detectors, which have the technology to scrutinize luggage and passengers for remains of explosive residue (Rex C. Curry, 2014). Furthermore, the gadgets can screen at passengers dress and luggage for concealed weapons.
The changes are useful in curbing another occurrence similar to the 9/11 tragedy. The changes are good to make but not substantial for a future event. The psychology employed by the security departments are in preventing recurrences of 9/11. However, it is not practical to argue that terrorist will use the same method to attack the United States. As the security levels tighten terrorist also get smarter. It will be the failure on the security side to believe that militia group cannot try to a way around the current measures. Terrorists are not ignorant to repeat the same method of attack without surety that it would yield to their target. Here are some of the steps the security department can employ to tighten safety and make it difficult for terrorists to create havoc.
Employ the use of missile disruptors and introduce body armors (Rex C. Curry, 2014). Maybe the terrorists may graduate to use flying machines other than planes into the buildings. This technology would also be useful to flight crews and marshals. The airports can use the technology employed by chemical engineers at the Michigan University, which aims at creating thin body armor for protection. The armor consists of fabric bonding of thin compressed layers of polymer, which is bullet proof (Rex C. Curry, 2014).
