It’s difficult to comprehend today, but in the past we were able to make it to the airport minutes prior to the departure time of a flight. We’d put our shoes on and coats on while we walked through a basic metal detector, and almost everyone could get to the gate with no boarder’s pass or an ID.
The 19 terrorists affiliated with al-Qaida who took overfour commercial jetliners on September. 11th, 2001 did not know this and benefited from insufficient security measures at airports walking across metal detectors in four security checkpoints effortlessly and carrying deadly weapons in their hands. The hijackers were able to hijack the planes and then make them into jet fuel-fueled missiles. They flew them towards two towers at the World Trade Center, the Pentagon and the field within Shanksville, Pa., killing more than three hundred people.
“It was so simplemany of us were shocked it didn’t happen earlier,” says Jeff Price who was security assistant director of Denver International Airport on Sept. 11 2001. He is now an expert in aviation security in Metropolitan State University of Denver.
Security for airports at the time was performed by private companies, typically employed by airlines, and with a few federal regulations. Security contracts typically went to the cheapest bidder.
“Before 9/11 security was virtually invisible and was intended to be so,” Price says. “It was intended to blend into the background that wasn’t really visible and did not hinder aircraft as well as airport operation.”
“You could get towards the gates at the last moment. It was not necessary to carry a boarding pass,” Price says. “All you required to do was go to the checkpoint for securitythere were no questions or ID required.”
It was a complete change on September 11, 2001. 11, 2001.
Nowadays, travelers stand on long queues at the security points that have wait times that could be more than an hour. We remove our shoes and empty our pockets, then take laptops and other gadgets from our carry-on bags prior to going through high-resolution full-body scanners. While our bags are scanned by 3D-imaging X-ray machines. Don’t forget to pack your liquids that weigh 3.4 grams or less from your carry-on bag.
We may also enroll in the most reputable or trusted traveler programs, such as PreCheck and give up some of our privacy the hope of having more speedy screening.
Aviation security experts admit that prior 9/11, nobody could have imagined suicide terrorists who would make use of commercial aircrafts as weapons, and be willing to commit suicide in order to murder hundreds of innocent victims.
In the present, homeland security officials from the federal government are working to envision the impossible and strengthen defenses to stop the constantly evolving and increasing threats to security of aviation.
Here’s an in-depth lookat how security at airports have changed over the last 20 years.
Sept. 11 2001: Terrorists take over and destroy four passenger aircrafts
The 19 hijackers waited for their flight at the airport in Portland, Maine, at Boston’s Logan International Airport, at Liberty International Airport in Newark, N.J., and at Dulles International Airport in the Washington, D.C., region.
If Mohamed Atta checked in at the Portland airport along with a fellow hijacker to board their short flight to Boston Atta was then chosen for further scrutiny under the system then called the CAPPS (Computer Assisted Prescreening of Passengers System). However, according to the 9/11 Commission Report, “Under the security regulations in force at the time, the sole consequence of Atta’s choice by CAPPS is that the luggage was removed from in the air until established that he had gotten on the plane. It did not hinder the plans of Atta.”
A few of the hijackers were detected by CAPPS at other airports. However, none was ever questioned, and they were permitted to board the same manner as Atta was -without the need for extra examination. When they passed through the metal detectors at airports, a few of hijackers set off alarms, however they were quickly cleared and allowed to go out after going through another metal detector, or being scanned using a handheld wand. It’s unclear exactly what caused the alarms to go off, however, as per the Commission Report of the 9/11 Commission Report, the hijackers utilized knives and/or razor blades during their attacks. These were likely carried with them or in their bags for carry-on. Even if the weapons were found, it wouldn’t be a factor.
“The FAA allowed knives of up to 4 inches length to be used on planes,” says Price, the expert in aviation security. “So even the hijackers had been caught with knives prior to getting on the airplane, security guards would have handed it over to the hijackers. “By 8:15 A.M. on the morning of September 11, 2001, Tuesday 2001 they had taken down all security measures that the American civil aviation security systems was in place to stop the possibility of a hijacking.” the 9-11 Commission Report states.
The months of September through October in 2001 have improved security at airports, less Americans flying, more waiting times in security lines
Following the crash of the planes on the twin towers and Pentagon The Federal Aviation Administration immediately ordered all commercial aircraft that were flying to be landed at the closest airport that was available. All flights were grounded until September. 14. When air travel began to begin, only a handful of Americans were ready to travel. In the weeks and days following the horrific terrorist attacks security at airports was immediately increased.
Armed National Guard soldiers joined local and state police in certain cities to assist in patrolling airports and check travelers. Box cutters, knives razors, and other kinds of blades were restricted as well as the list of items that are prohibited from aircrafts grew substantially.
Security guards at airports began scouring through bags of carry-on luggage and securing passengers according to Price said, was when the wait times at security lines at airports began to get longer, despite the fact that very few Americans had flights. Price says that authorities had been “slowing up the wait times at security checkpoints so that they could perform a more thorough inspection of baggage and passengers.”
Nov. 2001. The Aviation and Transportation Security Act establishes the TSA Checked baggage is screened with X-rays
Congress approved as well as President George W. Bush signed the law that would establish the Transportation Security Administration, which will be part of the newly-created Cabinet level Department of Homeland Security.
In addition to establishing the TSA in addition, it was also the time that Aviation and Transportation Security Act made it mandatory for checked baggage to be checked by X-rays. The Federal Air Marshal Service was extended to include more air marshals with guns on many more flights and the law also required airlines to strengthen the doors of their cockpits on their aircrafts to stop attacks from getting in.
The law also required that the TSA be responsible for security of all forms of transportation like train travel for passengers (including Amtrak) and intercity bus travel. Experts agree that the creation of the TSA was a significant advancement in enhancing security.
December 2001: The shoe bomber, and how the removal of shoes at airport security checkpoints got underway.
On December. 22nd, 2001 during the American Airlines flight from Paris to Miami the London-born criminal Richard Reid tried to detonate explosives he had packed inside his shoes. Passengers subdued, and then restrained Reid while the plane turned around to Boston which is the closest airport.
Investigators later found they believed that Reid had explosives in sufficient quantities to cause an opening in the fuselage on the aircraft, however, rainy conditions and Reid’s sweaty feet caused the fuse to be too wet to ignite. Reid was found guilty of eight charges related to terrorism in October 2002. He got sentenced for three life sentences, and 110 years in prison, without chance of parole. It led to TSA and airlines instructing passengers to take off their shoes while passing through terminal security points at the airport.
December 2002: using explosives detection systems, extremely detail 3D photos
The TSA is able to check every piece of checked luggage with the help of equipment that can check bags for explosives and other potentially dangerous weapons at every airport across the nation.
The technology employed in these screening systems has advanced dramatically in the past few years According to Deb Scovel the TSA Checkpoint and baggage manager in Chicago O’Hare International Airport, who claims today’s X-ray scanners are like CT scanners in hospitals.
“The imaging X-rays look at it from every angle,” says Scovel, “so it creates an all-encompassing image of what’s inside to show it from every angle of sight.” Scovel says that these 3D pictures are precise that “I can inform you of the distinction in Irish Spring and Dove soap Yes I am able to. Officers who have been around for a while have the ability to do this. It’s easy to tell the difference from an Apple and an Dell laptop. They’re extremely specific.”
April 3, 2003: Flight pilots are beginning carrying guns on flights, as well as other protections for cockpits.
The first pilots to be certified under a voluntary program that allowed the carrying of guns on flights. Bush approved the Arming Pilots Against Terrorism Act into law in November 2002 as well as the TSA began to train flight deck personnel on how to carry firearms aboard and if required, shortly after.
Also in April 2003 the TSA declared the airlines that had fulfilled the requirement of strengthening the doors to their cockpits on all of their fleet of aircrafts.
The pilots and unions continue to push for further cockpit barriers and fortifications in order to ensure they are safe from attacks external to the cockpit.
August 2006: liquids are banned as well as shoe removal is mandated, and air marshals were added
British authorities thwarted the plot of a terrorist group to explode liquid explosives aboard 10 commercial planes en route from London to cities across Canada, the U.S. and Canada. U.K. prosecutors alleged the attackers planned to disguise explosives in soft drinks 500 milliliter plastic bottles that were branded.
In the end, the TSA has banned all aerosols, gels, and liquids from carry-on luggage for passengers.
In September 2006 the TSA lifted its restriction on liquids and changed its rules to permit airline passengers to carry gels, liquids and aerosols in bottles of 3.4 pounds or less one clear, resealable 1 quart plastic bag. The bag was required to take off from the carry on luggage during security screening.
August 2006 was also the month that the TSA started to mandate that travelers take off their shoes to allow them to be checked for explosives at the security checks at airports.
The TSA also started deploying more air marshals from the federal government, for example, when flying internationally.
The month of March in 2008 Canine teams join security at airports
While bomb-sniffing dogs were utilized in a limited capacity part of the security measures for transportation and security, in the year 2000, the TSA started deploying teams of canines to assist with the security screening process for cargo that is loaded onto passenger aircrafts on U.S. airports.
The program then extended to employ dogs to look for explosive substances on passengers as well as inside carry-on bags and checked bags.
December 2009 December 2009: the “underwear bomber” and the introduction of body scanners for the full body.
At Christmas Day 2009 aboard an Northwest Airlines flight from Amsterdam to Detroit Al-Qaida radical Umar Farouk Abdulmutallab aimed to explode an explosive device he concealed inside his underwear.
Abdulmutallab later confessed to FBI officers that he had been tracking the plane’s flight path in the seat’s monitor in order to destroy the plane on U.S. soil. Within the briefs he was carrying explosive chemicals that could ignite when mixed. After he went into the toilet of the plane to finish his preparations the pilot returned to his seat and used an instrument in order to combine the substances.
However, the volatile mix did not go off as he planned probably due to excessive moisture from the chemicals that were in his pants for a long time. The mixture only ignited and seriously burned Abdulmutallab who attempted to take his pants off before his fellow crew members and passengers took him down.
Abdulmutallab later confessed to guilt of a crime and received a life sentence prison.
In reaction to the attack, in which the terrorist was able to get explosives that were dangerous through security, in March 2010, the TSA began to install hundreds of scanners for full body using sophisticated imaging technology.
In the year 2010’s final days, approximately 500 such machines were in use all over the country.
December 11, 2011: TSA PreCheck begins, verified travelers pay to have less security lines
With millions of people passing through security checkpoints of the TSA’s airports each year, the agency needed more effective methods to determine the difference between who is dangerous. The agency therefore launched its renownedas a trusted traveler PreCheck program that offers speedy screening to those who are willing to pay the cost and go through a more thorough background investigation.
The TSA states that it conducts risks assessments on passengers before they arrive at checkpoints at airports through these thorough background checks. The vetted travellers pay $85 for five years of membership and are able to undergo a less invasive security line and are no longer required to remove shoes or belts.
The TSA is adamant that it can focus efforts on more high-risk and unidentified travelers.
July 2015 TSA fail undercover testing
The inspector general of the TSA stated that 90% of the times, TSA officers failed to find explosives, weapons as well as other items prohibited by the undercover officers who were able to sneak through airport security checkpoints.
The staggeringly high rate of failure caused the TSA to reassign Melvin Carraway, who was at the time TSA’s acting director. This also brought about major changes to TSA methods of training, such as increased screening as well as more random searches.
June and March 2016: Attack outside Turkish border security at airport, worries about soft targets
In June of 2016 Three suicide bombers that were refused entry at a security checkpoint in the airport began firing semiautomatic weapons, before detonating explosive belts in Ataturk International Terminal at the airport in Istanbul and killed themselves along with 45 others and suffering more than 200 injuries.
The deadly attack followed the aftermath of a similar terrorist attack that was coordinated within three weeks prior that claimed the lives of 32 victims and injured over 300 people at the airport terminal and a subway station located in Brussels. The incident raised concerns regarding what security experts refer to as soft targets — zones outside of the security perimeter that huge crowds of people line up in baggage checkpoints, stand at kiosks and check-in counters or line up for security checkpoints.
Certain critics, such as anti-terrorism experts Tom Mockaitis at Chicago’s DePaul University claim it reveals the flaws in security.
“I’ve witnessed in this country us spend literally millions of dollars in what I would call a placebo securityhigh-visibility measures such as guards wearing armed uniforms walking across our airports that they create a feeling of wellbeing and a sense of security but not providing any added value,” Mockaitis told NPR in July of 2016.
March 2017: laptop ban
The Trump administration has, citing threats from reliable intelligence sources has barred travellers from certain nations from bringing laptops, tablets, and other electronic devices that are large in the cabin of international flights that connect to America. United States.
John Kelly, secretary of homeland security at the time, stated that intelligence suggested that terrorists were making bombs that were powerful enough to destroy an airplane, yet small enough to fit within these devices. It was reported that the laptop ban was affecting passengers from 10 airports across eight countries with majorities of Muslims.
“We did not feel in the moment that foreign airports had the same level of security at first that would give me confidence that they would be able to detect this device. The airports in these destinations,” Kelly said a few years after the prohibition was put in place.
The laptop ban was lifted in July of 2017.
June 2017 Face recognition biometric screening, privacy issues
In 2017, a few airlines, along with the TSA have begun tests of facial recognition technology which allows customers’ facial features to serve as passengers’ boarding cards.
The system will take a photograph and matches it with a photo that is on file with the airlines and speeds up the screening process and offering the customer with greater convenience. Additionally, since users of the system are required to be registered in the federal government’s known-traveler programme which provides an additional level of protection.
However, this and other biometric screening methods, which may allow government officials to monitor your movements at home as well as abroad, can raise privacy concerns as The NPR’s Asma Khalid wrote.
Security experts from the aviation industry say the TSA’s efforts in expanding the use of biometrics and facial recognition screening were significantly hampered by the COVID-19 epidemic, however, it could accelerate within the next few years.
September 2021: Still need to improve, but layers of soft and hard security
TSA officials claim that aviation security is constantly evolving to meet constantly changing threats. They employ a multi-layered approach that includes intelligence, surveillance and technology. The agency employs over 65,000 staff members and is spending billions of dollars every year to remain two steps ahead of possible terrorists from both the US and abroad.
“People are very imaginative. The threats are very imaginative,” says Louis Traverzo the TSA’s deputy national security director. He continues: “It’s up to us to be aware of this and it’s on us to examine those issues and develop ways to stop the strategies” that terrorists could develop.
There hasn’t been a single successful attack on commercial airlines in the U.S. in the 20 years since 9/11. experts from outside agree that, while there’s still need to improve but the TSA has proven successful in preventing another terrorist attack.
