9/11 Commissioner Bob Kerrey will mention in a public hearing, “In March 2001, another CSG [Counterterrorism Security Group] item on the agenda mentions the possibility of alleged bin Laden interests in ‘targeting US passenger planes at the Chicago airport,’ end of quote.”
[9/11 Commission, 3/24/2004] No newspaper has ever mentioned this warning, which presumably remained classified aside from this one accidental mention by Kerrey.
March 2001: Senior Military Officials Informed of Able Danger Program
During a briefing on another classified program called Dorkawk Galley, Able Danger is again brought up. This briefing, given by Lt. Col. Anthony Shaffer, is attended by Vice Adm. Thomas Wilson, director of the Defense Intelligence Agency; Richard Schiffrin, an attorney at DOD; and Stephen Cambone, Special Assistant to the Secretary and Deputy Secretary of Defense. [Government Security News, 9/2005; Office of Congressman Curt Weldon, 9/17/2005 Sources: Curt Weldon] In mid-September 2005, Weldon will say, “I knew that the Clinton administration clearly knew about this.” Referring to this meeting and another meeting with the Joint Chiefs of Staff (see Early 2001), he will add, “Now I know of at least two briefings in the Bush administration.” He calls these two briefings “very troubling.” He wants to know what became of the information presented in these briefings, suggesting it shouldn’t have been destroyed as part of the other Able Danger data purges.

March 2001: US Holds Intelligence Summit on Terrorist Threat
Counterterrorism “tsar” Richard Clarke organizes an intelligence summit on the terrorist threat to the US. The summit takes place at the National Reconnaissance Office in Virginia, and three dozen analysts are in attendance. One important topic of discussion is whether al-Qaeda could obtain a nuclear weapon. [Levy and Scott-Clark, 2007, pp. 305]
March-May 2001: FAA Briefs Airports on Security; They Cite, Then Dismiss Possibility of Planes as Weapons
A series of top-secret security briefings are given to airport officials at the top 19 airports in the US. The airports warned include those at Boston, Washington, and Newark, which are eventually used by the hijackers. A 9/11 Commission Report on this later notes, “The briefings highlight the threat posed by terrorists in general and bin Laden in particular, including his threats against aviation. The renewed interest in hijacking by terrorist groups [is] also covered.” The briefings note that if “the intent of the hijacker is not to exchange hostages for prisoners, but to commit suicide in a spectacular explosion, a domestic hijacking would probably be preferable.” But they also note that such a hijacking would be harder to carry out. Around the same time, the FAA distributes an unclassified CD-ROM presentation to airlines and airports. “The presentation cite[s] the possibility that terrorists might conduct suicide hijackings but state[s]: ‘Fortunately, we have no indication that any group is currently thinking in that direction.’” This briefing and presentation doesn’t lead to any upgrade in security or improved passenger screening at the airports. Apparently, the information isn’t widely shared with pilots, flight attendants, passenger screeners, and the like, and it doesn’t lead to any specific FAA advisories or actions. [New York Times, 2/10/2005; Newsday, 2/11/2005; New Jersey Star-Ledger, 2/11/2005] For instance, Dave Machett, a pilot who is president of the grassroots organization Airline Pilots Security Alliance, says that “Not one word” reached the pilots. “The flight crews were kept completely in the dark about this growing threat.”
[Newsday, 2/11/2005] 9/11 Commissioner Tim Roemer comments, “The FAA deserves to be raked over the coals for ignoring the warnings and being more concerned about reducing air traffic congestion than dealing with possible terrorist attacks.”

March-April 2001: Taliban Envoy Comes to US and Meets with High-Ranking Officials about Handing over Bin Laden
Taliban envoy Rahmatullah Hashimi meets with reporters, middle-ranking State Department bureaucrats, and private Afghanistan experts in Washington. He carries a gift carpet and a letter from Afghan leader Mullah Omar for President Bush. He discusses turning bin Laden over, but the US wants to be handed bin Laden and the Taliban want to turn him over to some third country. A CIA official later says, “We never heard what they were trying to say. We had no common language. Ours was, ‘Give up bin Laden.’ They were saying, ‘Do something to help us give him up.’… I have no doubts they wanted to get rid of him. He was a pain in the neck.” Others claim the Taliban were never sincere. About 20 more meetings on giving up bin Laden take place up until 9/11, all fruitless. [Washington Post, 10/29/2001] Allegedly, Hashimi also proposes that the Taliban would hold bin Laden in one location long enough for the US to locate and kill him. However, this offer is refused. This report, however, comes from Laila Helms, daughter of former CIA director Richard Helms. While it’s interesting that this information came out before 9/11, one must be skeptical, since Helms’ job was public relations for the Taliban. [Village Voice, 6/6/2001] Hashimi will mention to a reporter in June 2001 that he was in the US for a total of six weeks. [United Press International, 6/14/2001] According to one article at the time, Hashimi meets with “several senior officials from the State Department, CIA and National Security Council but also from the non-governmental organization Council on Foreign Relations.” Secretary of State Colin Powell is reportedly irate at the meetings because he had not been informed that high level officials would be meeting with Hashimi in the US. He blames CIA Director George Tenet “having laid on a red carpet for [Mullah] Omar’s adviser.” [Intelligence Newsletter, 4/19/2001] Hashimi reportedly directly meets with Tenet. [Irish Times, 11/19/2001]
March-April 2001: Al-Qaeda Defector Describes Plot to Hijack US Airplane
In March 2001, the ISI learns that one of bin Laden’s operatives, who is working on a sensitive al-Qaeda job in Afghanistan, has been providing information to the CIA at the US consulate in Peshawar, Pakistan. The operative, whose CIA codename is “Max,” becomes worried that the ISI will disclose to al-Qaeda his dealings with the CIA. The next month, ABC News reporters Chris Isham and John Miller meet with Max and help him defect to the US and talk to the FBI. Max tells the reporters that in 1999 and 2000 he was trained as part of a small group by Saif al-Adel, one of al-Qaeda’s top leaders. Asked by Isham and Miller whether al-Qaeda is planning any operations targeting the US, he describes a plan to hijack an airplane carrying a US senator or ambassador and then use the dignitary to bargain for the release of the “Blind Sheikh,” Sheikh Omar Abdul-Rahman. US intelligence learned of the same basic plot idea in 1998 (see 1998). Max does defect and will be extensively debriefed by the FBI. [Miller, Stone, and Mitchell, 2002, pp. 282] In May 2001, a Senior Executive Intelligence Brief (SEIB) will be sent to top White House officials warning that “terrorist groups [are] cooperating on [a] US hostage plot”(see May 23, 2001). It is not known for how long Max was talking to the CIA or what he told them before he was exposed, but his account contradicts assertions that US intelligence did not have any well placed informants in al-Qaeda in Afghanistan. An Afghan named “Ahmed” defects around the same time and there are similarities between his case and that of Max, but it is unknown if they are in fact the same person or not (see April 2001).
March-April 2001: 9/11 Hijacker Atta Visits Tennessee Airport; Asks About Nearby Chemical Plant and About Buying Plane
Two Middle Eastern men believed to be 9/11 hijackers Mohamed Atta and Marwan Alshehhi land a small plane at Martin Campbell Air Field, near the small town of Copperhill, Tennessee. Danny Whitener, a salvage-car dealer, is tending his plane at the time. The pilot, who calls himself “Mo,” speaks to Whitener for about 15 minutes, aggressively questioning him about a nearby chemical plant and what chemicals are kept there, about a nearby dam, and about two nearby nuclear power plants. According to Whitener, the pilot, who after 9/11 he is convinced was Mohamed Atta, tells him their plane is rented, and that they have flown from Lawrenceville, Georgia, which is about 60 miles south of Copperhill. This would concur with reports of Atta and Alshehhi twice renting a Piper Warrior plane from a Lawrenceville flight school around this time (see (January 25-Early March, 2001)). However, Whitener says their plane on this occasion is a Cessna, which has a very different design to a Warrior. About a month later, according to the airport’s manager John Rutkosky, a man resembling Atta again arrives, this time in an expensive-looking sports car, and inquires about buying a plane. [Associated Press, 10/19/2001; WBIR (Knoxville), 10/19/2001; Dawn (Karachi), 11/25/2001; Washington Post, 12/16/2001]
March-August 2001: 9/11 Hijacker Atta Familiarizes Himself with Flying Crop-Duster Planes
In March and August 2001, 9/11 hijacker Mohamed Atta visits a small airport in South Florida and asks detailed questions about how to start and fly a crop-duster plane. People there easily recall him because he was so persistent. After explaining his abilities, Atta is told he is not skilled enough to fly a crop-duster. [Miami Herald, 9/24/2001] Employees at South Florida Crop Care in Belle Glade, Florida, later tell the FBI that Atta was among the men who in groups of two or three visited the crop dusting firm nearly every weekend for six or eight weeks before the attacks. Employee James Lester says, “I recognized him because he stayed on my feet all the time. I just about had to push him away from me.” [Associated Press, 9/15/2001] Yet, according to US investigators, Atta and the other hijackers gave up on the crop-duster idea back around May 2000.
March 2001 and After: 9/11 Hijackers Continue to Associate with Al-Qaeda-Linked Imam Al-Awlaki
After living together in Phoenix since December 2000, 9/11 hijackers Hani Hanjour and Nawaf Alhazmi move to Falls Church, Virginia, where imam Anwar al-Awlaki preaches. [Washington Post, 9/10/2002; 9/11 Commission, 1/26/2004] They live only a few blocks from where two nephews of Osama bin Laden with ties to terrorism go to work (see February-September 11, 1996 and June 1, 2004). They continue to live there off and on until around August. They begin attending the Dar al Hijrah mosque. [Washington Post, 9/10/2002] When they and hijacker Khalid Almihdhar lived in San Diego in early 2000, they attended a mosque there led by al-Awlaki. This imam moved to Falls Church in January 2001, and now the hijackers attend his sermons at the Dar al Hijrah mosque. Some later suspect that al-Awlaki is part of the 9/11 plot because of their similar moves, and other reasons: 
The FBI says al-Awlaki had closed door meetings with hijackers Nawaf Alhazmi and Khalid Almihdhar in 2000 while all three of them were living in San Diego (see February-August 2000). [US Congress, 7/24/2003 
] Police later find the phone number of al-Awlaki’s mosque when they search “would-be twentieth hijacker” Ramzi bin al-Shibh’s apartment in Germany. [US Congress, 7/24/2003 ] The FBI was investigating al-Awlaki for ties to Islamic militant groups in early 2000 (see June 1999-March 2000). A neighbor of al-Awlaki later claims that, in the first week of August 2001, al-Awlaki knocked on his door and told him he is leaving for Kuwait: “He came over before he left and told me that something very big was going to happen, and that he had to be out of the country when it happened” (see Early August 2001). [Newsweek, 7/28/2003]
US officials will allow al-Awlaki to leave the US twice in 2002, but by 2008 they will conclude that he is linked to al-Qaeda attacks (see Early September 2006-December 2007 and February 27, 2008).
Early March 2001: Bush Administration Not Ready to Give CIA Expanded Authority to Assassinate Bin Laden
CIA Director George Tenet will claim in his 2007 book that he attempts to get new covert action authorities to fight bin Laden at this time. He says he wants to move from a defensive to offensive posture, but needs policy backing at a higher level to do it. He meets with Deputy National Security Adviser Stephen Hadley and gives him a list of expanded authorities the CIA is seeking to go after bin Laden. The authorities would permit the CIA or its partners to kill bin Laden without trying to capture him first. Tenet claims that he tells Hadley, “I’m giving you this draft now, but first, you guys need to figure out what your policy is.” The next day, Mary McCarthy, a CIA officer serving as National Security Council (NSC) senior director, calls Tenet’s chief of staff and asks the CIA to take the draft back. She says something to the effect, “If you formally transmit these to the NSC, the clock will be ticking (to take action), and we don’t want the clock to tick just now.” Tenet withdraws the draft. [Tenet, 2007, pp. 143-144] A deputy cabinet level meeting in July 2001 discusses the idea, but no action results (see July 13, 2001). The authorities will be granted a few days after 9/11. [Tenet, 2007, pp. 154]
