Investigators say Moussaoui attended mosques in Great Britain with suspected al Qaeda connections. One of those mosques is where convicted terrorist cleric Abu Hamza al-Masri was prayer leader.
He once bought training time on a commercial flight simulator, but school officials grew suspicious of him and contacted the local FBI.
Moussaoui has stated in court that he belongs to al Qaeda and is loyal to Osama bin Laden.
Prosecutors allege that Moussaoui attended a terrorist training camp in Afghanistan in 1998.
A search of Moussaoui's belongings shortly after 9/11 turns up Boeing 747 flight manuals, two knives, an aviation radio, information on aerial application of pesticides, and a notebook containing German telephone numbers.

1999 - French authorities place Moussaoui on a watch list.
February 26-May 29, 2001 - Moussaoui trains at the Airman Flight School in Norman, Oklahoma. He takes over 50 hours of flying lessons, but leaves without a pilot's license.

August 2001 - Minnesota FBI agents are refused permission, by their Washington office, to obtain a search warrant for Moussaoui's computer.
September 2001 - Moussaoui is identified as a possible 9/11 conspirator and potential fifth hijacker on Flight 93, the only plane with four instead of five hijackers. Also, the U.S. government states that he was to have piloted a fifth jetliner that would have targeted the White House.
December 11, 2001 - A federal grand jury indicts Moussaoui on six counts of conspiracy, the indictments directly related to the September 11 attacks and include conspiracy to destroy aircraft and murder United States employees.
January 2, 2002 - Moussaoui is arraigned. He declines to enter a plea for himself, saying," In the name of Allah, I do not have anything to plead." So U.S. District Judge Leonie Brinkema enters a not guilty plea on his behalf.
June 25, 2002 - At the arraignment for the revised indictment with amended charges, Moussaoui again refuses to enter a plea, and then tries to plead "no contest." Judge Brinkema refuses to accept the plea, believing Moussaoui does not understand the law, and enters a not guilty plea on his behalf.
July 16, 2002 - A third indictment of Moussaoui takes place, this one allowing prosecutors to spell out conduct that would warrant the death penalty.
July 18, 2002 - At his third arraignment, Moussaoui tries to plead guilty. The judge once more enters a not guilty plea and gives him one week to change his mind.
September 24, 2002 - Prosecutors file court papers that say a business card found in the wreckage of UA Flight 93 had a phone number on it that Moussaoui had telephoned. Prosecutors say it belonged to hijacker Ziad Jarrah, though they do not specify how they determined ownership of the card.
September 26, 2002 - The government acknowledges in court papers that it mistakenly turned over 48 classified documents to Moussaoui. All documents are eventually retrieved.
November 20, 2002 - An alleged al Qaeda leader in U.S. custody, Ramzi bin al-Shibh, tells interrogators that Moussaoui met with Khalid Sheikh Mohammed in Afghanistan in 2000. Mohammed eventually lost confidence in Moussaoui and decided to use him in the 9/11 plot only as a last resort, bin al-Shibh says.
May 14, 2003 - Moussaoui claims at the time of the 9/11 attacks he was preparing for a different al Qaeda operation to have occurred at a later date and in another country. Moussaoui's revelation -- his most detailed to date -- comes in a brief filed by defense attorneys assisting him with a pre-trial appeal.
June 3, 2003 - The case is heard by the 4th U.S. Circuit Court of Appeals, which is reviewing an order by the trial judge to allow Moussaoui to conduct a live video deposition with alleged September 11 attack coordinator Ramzi bin al-Shibh, a Yemeni national being detained as an enemy combatant at a military installation overseas. The government declares bin al-Shibh an "unavailable witness."
October 2, 2003 - U.S. District Court Judge Leonie Brinkema orders that the government will not be able to present evidence that Moussaoui had advance knowledge of or participated in the September 11 attacks. The sanctions are levied because federal prosecutors told Brinkema the government would not allow three high-ranking al Qaeda captives to testify in Moussaoui's trial or in pretrial depositions, as she previously ordered. Brinkema also strikes the death penalty from the indictment.

September 13, 2004 - The 4th U.S. Circuit Court of Appeals orders the Moussaoui case sent back to trial court so prosecutors and defense attorneys can work out a compromise on how to grant Moussaoui access to information supplied by al Qaeda captives that he says would help absolve him of the most serious charges against him.
March 21, 2005 - Without stating its reasons, the Supreme Court rejects his appeal, sending the case back toward trial. The trial, originally scheduled for September 2002, has been "indefinitely" delayed as the dispute over witness access moves through the courts.
April 22, 2005 - Moussaoui pleads guilty to all six counts against him. He could get the death penalty for his crimes. He says he was training to strike the White House with a 747.

February 26, 2008 - Moussaoui's lawyers ask a federal appeals court in Virginia to revoke Moussaoui's guilty plea, stating that his original lawyers were not permitted to discuss crucial, classified evidence about the case with him, and that this violated his U.S. constitutional rights.
