Airport security has evolved over the years, progressing from simple protection against conventional crimes in the early days to addressing more complex threats such as terrorism and hijackings. The evolution of airport security can be traced back to the 1960s when civil aviation became a target for politically motivated crimes, including terrorism and aircraft hijackings. Since then, security measures have been implemented and enhanced to ensure the safety of passengers, crew, and aircraft. Various organizations, such as the Transportation Security Administration (TSA) in the United States, have played a crucial role in developing and implementing security measures, including advanced technology for screening and identity verification. Countries like India have also stepped up their airport security in response to specific incidents, such as the 1999 Kandahar hijacking. The involvement of private companies and the use of biometric information have further contributed to the changing landscape of airport security worldwide.

What You'll Learn
Airport security before the 1960s
Airport security has evolved significantly over the years, with measures becoming increasingly stringent to address emerging threats and challenges. While it is challenging to ascertain the exact nature of airport security protocols before the 1960s, some insights indicate that security checks and measures were indeed in place during that early period of aviation history.
In the years before the 1960s, aviation security focused primarily on law enforcement presence and addressing hijacking incidents, which had been occurring since the dawn of aviation, with recorded cases as early as the 1930s. The first significant increase in security measures appears to have occurred in 1961, following the hijacking of a National Airlines flight to Cuba by Antulio Ramirez Ortiz, marking the first aerial hijacking of a U.S. passenger plane. This incident prompted the U.S. government to start placing armed guards on commercial flights when requested by airlines or the FBI.
While metal detectors were not widely used for passenger screening until later years, there is some evidence suggesting their presence in airports before the 1960s. Photographs and press articles indicate that early metal detectors may have been introduced to replace the manual searching of passengers. However, the effectiveness of these early security measures is uncertain, as hijacking incidents continued to occur.
Before the implementation of standardized security measures, some American airports and airlines took initiatives to screen select passengers who exhibited suspicious behaviour. This selective screening approach, however, proved insufficient in mitigating the evolving security threats. As a result, in December 1972, the Federal Aviation Administration (FAA) mandated a more comprehensive security measure, requiring airlines to search all passengers and their bags before boarding.
It is worth noting that, in the decades that followed, airport security underwent a constant evolution to address new challenges and threats, such as the terrorist attacks of September 11, 2001. The Transportation Security Administration (TSA) in the United States, for example, has continuously adapted its security procedures, employing advanced technology and enhancing screening measures to ensure safe travel.

The impact of 9/11 on airport security
Airport security has been a concern since the 1980s, with countries like France stepping up security measures after the 1986 terrorist attacks. India also enhanced its airport security after the 1999 Kandahar hijacking. However, the impact of 9/11 on airport security was significant and led to a series of new measures and policies worldwide, especially in the United States.
The Transportation Security Administration (TSA) in the US has been at the forefront of implementing and enhancing security measures post-9/11. They work closely with intelligence and law enforcement agencies to adapt security procedures based on evolving threats. One of the earliest measures taken by the TSA after 9/11 was the ban on liquids, gels, and aerosols in passenger carry-on baggage, implemented in 2006. This was due to the risk of liquid explosives, which are challenging to detect and pose a significant threat to aircraft security. The TSA also increased random screening of passengers and luggage, deployed more canine patrols, and strengthened air cargo security.
Over time, the TSA has continued to enhance security measures, including deploying advanced imaging technology, improving explosives trace detection, and implementing stronger domestic screening procedures for carry-on items. They have also introduced expedited screening programs like TSA PreCheck®, which makes risk assessments about passengers before they arrive at the airport, allowing for faster processing at security checkpoints.
In addition to the TSA's efforts, individual airports and countries have also taken initiatives to enhance security. For example, Los Angeles World Airports partnered with the TSA to pilot test two security checkpoint technologies in 2018, including facial recognition technology and enhanced Advanced Imaging Technology (eAIT) with increased detection capabilities. Similarly, the Canadian government privatized airport security in the 1990s, and individual airport authorities now contract private companies for security services.

The role of TSA in airport security
The Transportation Security Administration (TSA) is a US government agency that was created in 2001 to improve and enhance airport security. The TSA is part of the Department of Homeland Security and is responsible for screening passengers and their luggage, as well as inspecting airport facilities and equipment.
The TSA's primary mission is airport security and the prevention of aircraft hijacking. It is responsible for screening passengers and baggage at more than 450 US airports. The TSA develops key policies to protect the US transportation system, including highways, railroads, bus networks, mass transit systems, ports, pipelines, and intermodal freight facilities. It fulfills this mission in conjunction with other federal, state, local, and foreign government partners.
The TSA's screening procedures are intended to prevent prohibited items and other threats to transportation security from entering the sterile area of the airport. These procedures are developed in response to information on evolving threats to transportation security. The TSA works closely with intelligence and law enforcement communities to share information and adapt security procedures. Security measures begin long before passengers arrive at the airport, and the TSA counts on the traveling public to report any suspicious activities, such as unattended bags or individuals trying to enter restricted areas.
The TSA has also implemented programs such as TSA PreCheck® and CLEAR to expedite the security process for pre-approved travelers. These programs allow eligible travelers to go through a separate, faster security lane and skip certain steps, such as removing shoes and light jackets. Additionally, the TSA has enhanced security measures over time, including increased random screening of employees, additional canine patrols, stronger air cargo security, and improved identity verification standards.

The use of technology in airport security
Airport security has evolved over the years, with the adoption of new technologies playing a pivotal role in enhancing safety and efficiency. The primary objective of airport security is to safeguard the airport, the country, and its people from potential threats while ensuring the travelling public feels reassured and protected. This multifaceted role has driven the exploration of innovative technologies to address the dynamic nature of security challenges.
One notable example is the deployment of advanced imaging technology (AIT), which has been pivotal in strengthening security screening procedures. AIT encompasses various cutting-edge tools, such as full-body scanners and 3D CT scanners, that provide detailed visualizations of carry-on items and personal belongings. These scanners can detect prohibited items, including weapons and explosives, ensuring they never make it past security checkpoints. TSA, the Transportation Security Administration in the United States, has been at the forefront of implementing and refining AIT, continually enhancing its capabilities to address evolving threats.
In addition to AIT, the use of biometric identification and facial recognition technology has gained prominence in airport security. This technology streamlines the identification and verification process, enhancing efficiency and security. For instance, TSA PreCheck® in the United States offers expedited screening for trusted travellers by conducting risk assessments prior to their arrival at the airport. This programme utilises biographic information, fingerprints, and identity documentation to facilitate a seamless and secure travel experience.
Furthermore, the integration of IoT sensors and real-time data analytics has elevated airport security to new heights. IoT sensors enhance situational awareness, enabling security personnel to respond swiftly to incidents. Additionally, predictive maintenance capabilities ensure that security equipment remains operational at all critical times. This technology also provides valuable insights into passenger behaviour, allowing airports to optimise their retail, dining, and entertainment offerings.
The use of smart cameras and thermal imaging technology further underscores the pivotal role of technology in airport security. By deploying cameras at strategic locations within the terminal, security teams can monitor passenger behaviour and promptly detect any unusual or suspicious activities. Drones equipped with high-resolution cameras have also proven effective in patrolling vast airport areas, including runways and perimeter fences, providing comprehensive surveillance and enhancing security personnel's ability to identify potential security breaches.

International airport security standards
Airport security serves several purposes: to protect the airport and country from any threatening events, to reassure travellers that they are safe, and to protect the country and its people.
Airport security standards vary across the world, with some countries adopting stricter measures than others. For example, in Canada, airport security was previously handled by the Canadian Security Intelligence Service, the Royal Canadian Mounted Police (RCMP), and Transport Canada. However, since the 1990s, airport authorities have been responsible for general airport security, often contracting private companies and local police officers. Similarly, in the Netherlands, airport security is provided by a combination of the Royal Military Constabulary and private security firms. In contrast, countries like Australia have a centralised agency, the Australian Federal Police, that secures all airports in the country.
The Transportation Security Administration (TSA) in the United States has implemented various measures to enhance aviation security, both domestically and internationally. These include:
- Risk-based passenger pre-screening programs, such as Secure Flight, that identify low and high-risk passengers before their arrival by matching them against trusted traveller lists and watchlists.
- TSA PreCheck®, an expedited screening program that allows known and trusted travellers to bypass certain security measures, such as removing shoes, laptops, and light jackets.
- Enhanced screening procedures for carry-on items, requiring travellers to place personal electronic devices larger than a cell phone in bins for X-ray screening.
- Deployment of state-of-the-art technology, including automated screening lanes, advanced imaging technology, and CT scanners for improved threat detection.
- Increased collaboration with international partners to maintain and enhance aviation security standards at foreign airports with direct flights to the US.
Other countries have also adapted their airport security measures based on specific events or evolving threats. For instance, India strengthened its airport security after the 1999 Kandahar hijacking, with the Central Industrial Security Force taking charge under the Bureau of Civil Aviation Security. France established the Vigipirate program in response to terrorist attacks in 1986, deploying troops and increasing screening and ID check requirements.
To ensure safe travel, airport security standards must constantly evolve and adapt to address new threats and challenges. This includes the implementation of unseen measures, such as information sharing between security agencies and law enforcement, in addition to the more visible security checks experienced by travellers.
