PENTTBOM (sometimes referred to as PENTTBOMB [1] ) is the codename for the Federal Bureau of Investigation's probe into the September 11 attacks of 2001, the largest criminal inquiry in the FBI's history. Its name stands for "Pentagon/Twin Towers Bombing Investigation". The investigation was launched on September 11, 2001, and involved 4,000 special agents and 3,000 professional employees. [2] [3]
The FBI was able to identify the 19 hijackers within a matter of days as few suspects made any effort to conceal their names on flight, credit card, and other records. [4]
Three of the hijackers carried copies of an identical handwritten letter [5] [6] (in Arabic) that was found in three separate locations: the first, in a suitcase of hijacker Mohamed Atta that did not make the connection to American Airlines Flight 11 that crashed into the North Tower of the World Trade Center; the second, in a vehicle parked at Washington Dulles International Airport that belonged to hijacker Nawaf al-Hazmi; and the third at the crash site of United Airlines Flight 93 in Shanksville, Pennsylvania.
According to the testimony before the House Intelligence Subcommittee on Terrorism and Homeland Defense on October 3, 2001, given by J. T. Caruso, the Deputy Assistant Director of the FBI's Counterterrorism Division, "translations of the letter indicate an alarming willingness to die on the part of the hijackers." [7]
According to testimony by Susan Ginsberg, a staff member of the National Commission on Terrorist attacks upon the United States, in the January 26, 2004, Public Hearing: [8]
The passport of hijacker Satam al-Suqami was found a few blocks from the World Trade Center. [9] [10]
According to the 9/11 Commission, the passports of two of the Flight 93 hijackers were also found intact in the aircraft's debris field. [11]
The doctored passport of hijacker Abdulaziz al-Omari was found in Mohamed Atta's left-behind luggage. [11]
When examining Mohamed Atta's luggage, the FBI found important clues about the hijackers and their plans. His luggage contained papers that revealed the identity of all 19 hijackers, and provided information about their plans, motives, and backgrounds. [12] The FBI was able to determine details such as dates of birth, known and/or possible residences, visa statuses, and specific identities of the suspected pilots. None of these documents have been scrutinized by independent legal experts. [13]
The investigators were quickly able to link the 19 men to the terrorist organization al-Qaeda, by accessing their intelligence agency files. The New York Times reported on September 12 that: "Authorities said they had also identified accomplices in several cities who had helped plan and execute Tuesday's attacks. Officials said they knew who these people were and important biographical details about many of them. They prepared biographies of each identified member of the hijack teams, and began tracing the recent movements of the men." FBI agents in Florida investigating the hijackers quickly "descended on flight schools, neighborhoods and restaurants in pursuit of leads." At one flight school, "students said investigators were there within hours of Tuesday's attacks." [14] The Washington Post later reported that "In the hours after Tuesday's bombings, investigators searched their files on [Satam] Al Suqami and [Ahmed] Alghamdi, noted the pair's ties to [Nabil] al-Marabh and launched a hunt for him." [15]
On September 27, 2001, the FBI released photos of the 19 hijackers, along with information about the possible nationalities and aliases of many. [16]
On the day of the attacks, U.S. intelligence agencies also intercepted communications that pointed to Osama bin Laden. [17] It was quickly asserted that Osama bin Laden was responsible for the attacks, and other suspects were ruled out. Although he denied the attacks at first, Osama bin Laden later admitted full and sole responsibility for the attacks in a video tape. [18]

On September 11, 2001, 19 al-Qaeda terrorists took control of four commercial aircraft and used them as suicide weapons in a series of four coordinated acts of terrorism to strike the World Trade Center in New York City, The Pentagon in Arlington County, Virginia, and an additional target in Washington, D.C. Two aircraft hit the World Trade Center while the third hit the Pentagon. A fourth plane did not arrive at its target, but crashed into a field in Pennsylvania after a passenger revolt. The intended target is believed to have been the United States Capitol. As a result, 2,977 victims were killed, making it the deadliest foreign attack on U.S. soil, exceeding Japan's surprise attack on Pearl Harbor in Honolulu, Hawaii, on December 7, 1941, which killed 2,335 members of the United States Armed Forces and 68 civilians. The effort was carefully planned by al-Qaeda, which sent 19 terrorists to take over Boeing 757 and Boeing 767 aircraft, operated by American Airlines and United Airlines.
The September 11 attacks, commonly known as 9/11, were four coordinated Islamist suicide terrorist attacks carried out by al-Qaeda against the United States in 2001. That morning, 19 terrorists hijacked four commercial airliners scheduled to travel from the New England and Mid-Atlantic regions of the East Coast to California. The hijackers crashed the first two planes into the Twin Towers of the World Trade Center in New York City, two of the world's five tallest buildings at the time, and aimed the next two flights toward targets in or near Washington, D.C., in an attack on the nation's capital. The third team succeeded in striking the Pentagon, the headquarters of the U.S. Department of Defense in Arlington County, Virginia, while the fourth plane went down in rural Pennsylvania during a passenger revolt. The September 11 attacks killed 2,977 people, the deadliest terrorist attack in human history, and instigated the multi-decade global war on terror, fought in Afghanistan, Iraq, and elsewhere.
Various conspiracy theories allege that certain institutions or individuals had foreknowledge of the September 11 attacks in the United States in 2001. Some of the primary debates include whether the Bush administration or the United States Armed Forces had awareness of the planned attack methods, the precise volume of intelligence that American agencies had regarding al-Qaeda activities inside the United States, whether the put options placed on United Airlines and American Airlines and other trades indicated foreknowledge, and why the identities of the traders have never been made public.
American Airlines Flight 11 was a domestic passenger flight that was hijacked by five al-Qaeda terrorists on the morning of September 11, 2001, as part of the September 11 attacks. The hijacked airliner was deliberately crashed into the North Tower of the World Trade Center complex in New York City, killing everyone aboard the flight and resulting in the deaths of more than one thousand people in the top 18 stories of the skyscraper in addition to causing the demise of numerous others below the trapped floors, making it not only the deadliest of the four suicide attacks executed that morning in terms of both plane and ground fatalities, but also the single deadliest act of terrorism in human history and the deadliest plane crash of all time. The aircraft involved, a Boeing 767-223ER with 92 passengers and crew, was flying American Airlines' daily scheduled morning transcontinental service from Boston Logan International Airport in Massachusetts to Los Angeles International Airport in California.
At around 9:30 pm on September 11, 2001, George Tenet, director of the Central Intelligence Agency (CIA) told President George W. Bush and U.S. senior officials that the CIA's Counterterrorism Center had determined that Osama bin Laden and al-Qaeda were responsible for the September 11 attacks. Two weeks after the terrorist attacks on September 11, 2001, the Federal Bureau of Investigation connected the hijackers to al-Qaeda, a militant Salafist Islamist multi-national organization. In a number of video, audio, interview and printed statements, senior members of al-Qaeda have also asserted responsibility for organizing the September 11 attacks.
