Airport security for the two flights out of Newark and Washington Dulles had been provided by Argenbright Holdings Ltd, a company which had plead guilty to federal fraud charges in May 2000 because they had hired 1,300 untrained security guards, including several dozens with criminal records, at Philadelphia International Airport. The company is still on probation.

THE INVESTIGATION: U.S. Identified Some Elements of Hijack Plot in Advance, New York Times, 9/21/2001 Minetta Congressional testimony
All civilian airplane traffic in the United States was grounded until Thursday, September 13. United Airlines cancelled all flights worldwide temporarily. First stranded planes were allowed to go to their intended destinations, then limited service resumed. On Thursday night the New York area airports (JFK, La Guardia, Newark) were closed again, and were reopened Friday morning. The only traffic from La Guardia during the closure was a single C9C government VIP jet, departing at approximately 5:15PM on the 12th.
All train service through Union Station was suspended.
Beginning September 27, one-occupant cars were banned from crossing into Lower Manhattan from Midtown on weekday mornings, in an effort to relieve some of the crush of traffic in the city (the morning rush hour was lasting from 5:30 AM to noon), caused largely by the increased security measures put in place.

After the attack, the cell phone network of New York City was rapidly overloaded as traffic doubled over normal levels. Since three of the major broadcast networks had their transmission tower atop the North Tower (One World Trade Center), coverage was limited after the collapse of the tower.
Emergency relief efforts in both Lower Manhattan and at the Pentagon were augmented by volunteer amateur radio operators in the weeks after the attacks.
After the planes struck the World Trade Center, people inside made calls to loved ones; in many cases, the last ever heard from them.
AT&T eliminated any costs for domestic calls originating from the New York City area (212/718/917/646/347) in days following.

September 11, 2001 Terrorist Attack -
In Memoriam - Casualties - Survivors - Personal experiences - Memorials and Services
U.S. authorities believe that the hijackers were in two groups--six core organizers, who included the four pilots and two others, and the remaining 13, who came to the United States later, in pairs in the spring and summer of 2001 via the UAE.
The six organizers were the pilots--Mohammed Atta, Marwan Alshehhi, Ziad Jarrah, and Hani Hanjour--and Khalid Almihdhar and Nawaf Alhazmi.
Several of the terrorist hijackers appeared to be traveling with false passports, assuming the identities of other people. Saudis Saeed Alghamdi, Abdulaziz Alomari, and Waleed Alshehri, whose photographs have appeared on CNN and other media outlets, have spoken to Saudi newspapers since the attack.
Their profiles do not seem to match that of past suicide terrorists (young, poor, uneducated and indoctrinated): many were in their late twenties and thirties, most with college educations, and had lived for prolonged periods of time in western countries. 15 came from Saudi Arabia. The remaining four came from Egypt, the United Arab Emirates and Lebanon.
There have been variations in the spelling of the names of the alleged hijackers in differing accounts of the attacks- one good example being the Alshehris from Flight 11. This is because there is no one correct way of translating from Arabic script to English letters.

Three of the hijackers, along with Ramzi Binalshibh, Said Bahaji, and Zakariyah Essabar were members of the Hamburg, Germany cell. After Atta, Al-Shehhi, and Jarrah left for the United States, Binalshibh provided money to the conspirators. Riduan Isamuddin, aka Hambali, met with two of the hijackers in Kuala Lumpur in 2000. Hambali also gave money to alleged 20th hijacker Zacarias Moussaoui. The members of the cell fled Germany before the terrorist attacks.

Next in line to claim responsibility were the Taliban of Afghanistan. The Taliban government subsequently denounced the attack and claimed that it was not connected to Osama bin Laden, the terrorist living in Afghanistan who the U.S. government declared the prime suspect.
Although bin Laden's Al-Qaida organization has never explicitly claimed responsibility, it has praised the attacks and hinted that it was behind them and planning more. The group's spokesman, Sulaiman Abu Ghaith, said in a video sent to al-Jazeera and broadcast in October 2001: "Americans should know, the storm of the planes will not stop. ... There are thousands of the Islamic nation's youths who are eager to die just as the Americans are eager to live."
Furthermore, intelligence experts speak of a "short list" of prime suspects -- groups that possess both the means and the motive to carry out the crime. It appears certain that all hijackers have Arabic origins, and none are Afghani; moreover, both in their immense scale, careful planning and refraining from claiming responsibility, the attacks are reminiscent of Al-Qaida's previous attacks.
Virtually all world leaders, including traditional enemies of the United States such as Libyan president Qadhafi, Palestinian leader Arafat, Iranian president Khatami, and the Afghanistan Taliban government, denounced the attacks and expressed sympathy for the American people. An exception was Saddam Hussein, then ruler of Iraq, who called the attacks the fruits of U.S. crimes against humanity.
Various Arab- and Muslim-world news sources carried opinion pieces and articles that pointed to some form of Zionist conspiracy to frame the Arab world to the benefit of Israel. It is interesting to note that in a Gallup survey of 10,000 inhabitants of sample countries with a Muslim majority, only 18% believed that the Arabs responsible.
Worldwide, a significant minority see the attack as an outcome of past United States involvement in the Middle East and surrounding area. They believe that such acts of terrorism are only to be expected given the economic and cultural power of the United States and the multinational corporations which are identified with it. The creation of pockets of hatred, according to this viewpoint, is an inevitable consequence of the overwhelming outside economic pressure placed on poor countries with minimal control of their political destiny. Notwithstanding this, the majority of people in most nations also believe that terrorism is an absolute evil, and that cause does not equal justification. However, some people who believe this also criticize the US's War on Terrorism, fearing that a violent response will only continue the cycle.
While Jemaah Islamiah head Riduan Isamuddin, better known as Hambali, would not get the spotlight in the United States until after the Bali nightclub bombings, he had a hand in the planning of September 11. His front company, Konsojaya, which was founded in 1994, helped fund Manila-based Operation Bojinka, which was a massive planned terrorist attack that would be foiled on January 5, 1995, when Filipino police found the project on honcho Ramzi Yousef's laptop in his apartment after a chemical fire broke out in the apartment. Yousef would get arrested in Pakistan the following month, but Khalid Sheik Mohammed ran away, and used plans and lessons learned to help shape September 11.
Hambali's company was narrowly overlooked, so Hambali was able to go underground. He met with two of the September 11 hijackers, Khalid Almihdhar and Nawaf Alhazmi in the 2000 Al Qaeda Summit in January 2000. He also gave money to alleged "20th hijacker" Zacarias Moussaoui.
Hambali got arrested in Thailand on August 11, 2003.

Official document containing information from intelligence and criminal investigation as released by the British PM Tony Blair on his official webside, October 4, 2001: Responsibility for the terrorist atrocities in the United States, 11 September 2001. See:
Numerous investment firms housed in the World Trade Center lost hundreds of employees, including Cantor Fitzgerald and Marsh & McLennan.
Stock exchanges all over the world plummeted; many of them--including the London Stock Exchange--were evacuated. The New York Stock exchanges remained closed until the following Monday. Gold and oil prices spiked upwards. See also Stock market downturn of 2002.
Travel and entertainment stocks fell, while communications, pharmaceutical and military/defense stocks rose. Online travel agencies particularly suffered, as they cater to leisure travel.
The Times reported on 18th September that investigations are under way into the unusually large numbers of shares in insurance companies and airlines sold off before the attack, in London, Italy, Germany, Japan, Switzerland, France and the US
U.S. gas prices briefly shot up.
ScamBusters reported that some email pleas for relief funds for victims of the attacks were simply scams to procure credit card numbers from inexperienced web users. ScamBusters offered tips to help donors ensure their contributions went to the right places.
Tourism in New York City plummeted, causing massive losses in a sector which employed 280,000 people and generated $25 billion per year. In the week following the attack, hotel occupancy falls below 40 percent, and 3000 employees are laid off. Tourism and hotel occupancy also falls drastically across the nation.
Share prices of airlines and airplane manufacturers plummeted after the attacks. Midway Airlines, already on the brink of bankruptcy, shut down operations almost immediately afterwards. Other airlines were threatened with bankruptcy. Tens of thousands of layoffs were announced in the following week.
The New York City projected budget deficit for the 2003 fiscal year which begins July 2002 ballooned from $2-$2.5 billion to approximately $4 billion, though most direct expenses related to the rescue and recovery effort are to be covered by the expected $40 billion in federal aid. However, the related drop in tourism and Lower Manhattan tax revenue is not expected to be covered.
Over the following months and years, western economies (the United States in particular) diverted massive sums away from productive activities and into activities that produce no economic return or even negative return, notably airport and aircraft security (producing long delays and depressing passenger numbers) and military action against states said to support terrorism. The total cost of the western reaction to the September 11th attacks is unknown, but clearly vastly higher than the cost of the attacks themselves.

Cell phones and in-plane credit card phones played a major role during and after the attack, starting with hijacked passengers who called family or notified the authorities about what was happening. Passengers and crew who made calls include Todd Beamer, Mark Bingham, Peter Hanson, Jeremy Glick, Barbara K. Olson, Madeline Amy Sweeney

There were reports that the Palestinian group DFLP (Democratic Front for the Liberation of Palestine) took responsibility for the crashes, but this was denied by a senior officer of the group soon after. There are filmed reports of celebrations on the West Bank, although according to articles in the German magazine Stern and the Swedish daily newspaper Dagens Nyheter at least one of them was staged. Palestinian leader Yasser Arafat denounced the attacks, saying it was counterproductive to any peace between Israelis and Palestinians.External Links & References

It is usually claimed that the September 11, 2001 Terrorist Attack had immediate and far-ranging economic effects. The overwhelming majority of these effects, however, were not a direct result of the terrorist attacks, but a consequence of the subsequent actions of western people and their governments. This is particularly so with regard to long-term economic changes, such as the worldwide decline in the aviation industry, which still shows no sign of recovering. Nevertheless, it is convenient to discuss the effects of the attacks themselves and the effects of later actions by western economies together.
