After 9/11, both the SEC and the Secret Service announce probes into an unusually high volume trade of five-year US Treasury note purchases around this time. These transactions include a single $5 billion trade. The Wall Street Journal explains: “Five-year Treasury notes are among the best investments in the event of a world crisis, especially one that hits the US. The notes are prized for their safety and their backing by the US government, and usually rally when investors flee riskier investments, such as stocks.” The value of these notes has risen sharply since the events of September 11. The article also points out that with these notes, “tracks would be hard to spot.”

Early September 2001: Bin Laden’s Intercepted Phone Calls Discuss an Operation in the US Around 9/11 Date
According to British inside sources, “shortly before September 11,” bin Laden contacts an associate thought to be in Pakistan. The conversation refers to an incident that will take place in the US on, or around 9/11, and discusses possible repercussions. In another conversation, bin Laden contacts an associate thought to be in Afghanistan. They discuss the scale and effect of a forthcoming operation; bin Laden praises his colleague for his part in the planning. Neither conversation specifically mentions the WTC or Pentagon, but investigators have no doubt the 9/11 attacks were being discussed. The British government has obliquely made reference to these intercepts: “There is evidence of a very specific nature relating to the guilt of bin Laden and his associates that is too sensitive to release.” These intercepts will not be made public in British Prime Minister Tony Blair’s presentation of al-Qaeda’s guilt because “releasing full details could compromise the source or method of the intercepts.”

Early September 2001: Iranian Inmate in Germany Warns of Imminent Attack on WTC
An Iranian man known as Ali S. in a German jail awaiting deportation repeatedly phones US law enforcement to warn of an imminent attack on the WTC in early September. He calls it “an attack that will change the world.” After a month of badgering his prison guards, he is finally able to call the White House 14 times in the days before the attack. He then tries to send a fax to President Bush, but is denied permission hours before the 9/11 attacks. German police later confirm the calls. Prosecutors later will say Ali had no foreknowledge and his forebodings were just a strange coincidence. They will say he is mentally unstable.

Early September 2001: Seattle Security Guard Tells Friend of Impending Attack
A few days before 9/11, a Seattle security guard of Middle Eastern descent tells an East Coast friend on the phone that terrorists will soon attack the US. After 9/11, the friend tells the FBI, and passes a lie detector test. The security guard refuses to cooperate with the FBI or take a lie detector test. He is not arrested—apparently the FBI determines that while he may have had 9/11 foreknowledge, he was not involved in the plot. [Seattle Post-Intelligencer, 10/12/2001]
Early September 2001: New York Mosque Warning: Stay Out of Lower Manhattan on 9/11
Shortly before 9/11, people attending an unnamed mosque in the Bronx district of New York City are warned to stay out of lower Manhattan on 9/11. The FBI’s Joint Terrorist Task Force interviews dozens of members of the mosque, who confirm the story. The mosque leadership denies any advanced knowledge and the case apparently remains unsolved.

Early September 2001: Rumors in New York City’s Arab-American Community About Attacks
A veteran detective involved with post-9/11 investigations later claims that rumors in New York City’s Arab-American community about the 9/11 attacks are common in the days beforehand. The story “had been out on the street” and the number of leads turning up later is so “overwhelming” that it is difficult to tell who knows about the attacks from secondhand sources and who knows about it from someone who may have been a participant. After 9/11, tracking leads regarding Middle Eastern employees who did not show up for work on 9/11 are “a serious and major priority.”

Early September 2001: Accounts Place Three 9/11 Hijackers on East and West Coasts at the Same Time
The standard accounts place 9/11 hijackers Hani Hanjour, Nawaf Alhazmi, and Khalid Almihdhar on the East Coast for the entire time in the weeks before the attacks (see (August 23-September 10, 2001)). [New York Times, 9/21/2001; Associated Press, 9/21/2001; Newsday, 9/23/2001; CNN, 9/26/2001; St. Petersburg Times, 9/27/2001; South Florida Sun-Sentinel, 9/28/2001; New York Times, 11/6/2001; US Congress, 9/26/2002] However, neighbors at Parkwood Apartments in San Diego where the three lived in 2000 are clear in their assertions that all three were there until days before 9/11. For instance, one article states, “Authorities believe Almihdhar, Hanjour and Alhazmi… moved out a couple of days before the East Coast attacks.” [KGTV 10 (San Diego), 11/1/2001] Ed Murray, a resident at the complex, said that all three “started moving out Saturday night-and Sunday [September 9] they were gone.” [KGTV 10 (San Diego), 9/14/2001; KGTV 10 (San Diego), 9/20/2001] This is the same day that Alhazmi is reportedly seen in an East Coast shopping mall. [CNN, 9/26/2001] As with previous reports, neighbors also see them getting into strange cars late at night. A neighbor interviewed shortly after 9/11 said, “A week ago, I was coming home between 12:00 and 1:00 A.M. from a club. I saw a limo pick them up. It was not the first time. In this neighborhood you notice stuff like that. In the past couple of months, I have seen this happen at least two or three times.” [Time, 9/24/2001] To add to the confusion, there have been reports that investigators think Almihdhar is still alive and the Chicago Tribune says of Alhazmi, Almihdhar, and Hanjour: “The most basic of facts—the very names of the men—are uncertain. The FBI has said each used at least three aliases. ‘It’s not going to be a terrible surprise down the line if these are not their true names,’ said Jeff Thurman, an FBI spokesman in San Diego.” [Chicago Tribune, 9/30/2001]
Early September 2001: Hambali Aware of Attack Date for 9/11 Plot
Hambali, a top al-Qaeda leader in Southeast Asia, appears aware of the date of the 9/11 attacks. Mohammed Mansour Jabarah, a young Canadian citizen who recently joined al-Qaeda, meets Hambali in Karachi, Pakistan, to get instructions in carrying out an attack in Southeast Asia. Hambali tells him, “Make sure you leave before Tuesday” – September 11. Jabarah does heed the warning and flies to Southeast Asian on September 10. He will be arrested in 2002 and deported to Canada, where he will make a full confession about his al-Qaeda contacts (including an unheeded warning about the October 2002 Bali bombings (see August 21, 2002). [National Post, 1/18/2003] Khalid Shaikh Mohammed (KSM) is also in Karachi and working with Jabarah and Hambali on future Southeast Asian plots, and KSM also warns Jabarah to travel before September 11.

Early September 2001: Pakistani Student Says WTC Towers ‘Won’t Be Here Next Week’
At New Utrecht High School, in Brooklyn, New York City, about one week before 9/11, a Pakistani student in a bilingual class points at the WTC during a heated political argument and declares, “Look at those two buildings. They won’t be here next week.” The teacher notifies New York police after 9/11, who in turn notify the FBI. The status of the FBI investigation into this incident is unknown as of early October 2001.

Early September 2001: 9/11 Hijackers Alhazmi and Almihdhar Practice Using Flight Simulator Software
9/11 hijackers Nawaf Alhazmi and Khalid Almihdhar are seen to practice using flight simulator software while at an apartment in San Diego. A neighbor will later say he often saw a computer switched on inside the men’s apartment running a flight simulator program, “I could look in, if the door was open. You could always see a flight simulator type of thing, with airplanes on it.” According to eyewitnesses, this takes place shortly before 9/11. Alhazmi and Almihdhar lived in San Diego in 2000 (see January 15-February 2000 and February 2000-Early September 2001), but are usually thought to be on the East Coast in the summer of 2001 (see August 27-September 1, 2001 and September 5-10, 2001). However, there are multiple eyewitness reports of them being seen in the San Diego area around this time, back in the same apartment where they had lived in 2000 (see Early September 2001).
