Complete 911 Timeline

Some of the recently added entries go into more detail about the 9/11 Commission, which discovered the FAA was withholding documents from it in September 2003 and issued its first subpoena for them a month later. Soon after, the commission also subpoenaed the Pentagon, despite a last-ditch bid to avert it by the commission’s Vice Chairman Lee Hamilton, a good friend of Defense Secretary Donald Rumsfeld. In addition, Commissioner John Lehman repeatedly told the White House of Saudi links to the 9/11 plotters, but the administration was uninterested.

On the day of 9/11, fighters launched from Langley Air Force Base were given the wrong coordinates for Washington at about 9:40 a.m., Otis Air Force Base was ordered to launch all fighters at about 10:20 a.m., and a security officer became trapped in WTC 7 around 10:00 a.m.

The very first entry in the timeline has also changed, and is now for a 1968 advert showing an airliner striking one of the WTC buildings, something that nearly happened in 1981.

Finally, in the late 1990s Yemeni authorities saw Abu Hamza al-Masri, an informer for the British security services, as a terrorist leader in Yemen.
