Note the different times on the two time stamps, one in the middle, one at the bottom. [Source: FBI]Minutes after arriving at the Portland airport, hijackers Mohamed Atta and Abdulaziz Alomari pass through the airport’s single security checkpoint, on the way to boarding their 6 a.m. flight to Boston. The checkpoint has a surveillance camera pointing at it, which captures them as they go through. [Time, 9/24/2001; 9/11 Commission, 8/26/2004, pp. 2-3 ] Some reports say the pair passes through at 5:53 a.m. [Associated Press, 9/14/2001; New York Times, 9/14/2001; Washington Post, 9/14/2001] Other reports put it earlier, at 5:45 a.m. [Portland Press Herald, 10/5/2001; Federal Bureau of Investigation, 10/14/2001; 9/11 Commission, 8/26/2004, pp. 3 ] Strangely, when stills from the surveillance camera are later publicly released, they show two time stamps, one of 5:45 and another of 5:53. [Guardian, 9/21/2001; Federal Bureau of Investigation, 10/14/2001] When they’d checked in just minutes earlier, Atta and Alomari were observed wearing ties and jackets (see 5:43 a.m. September 11, 2001). But in the security video footage, they have just open-necked shirts, with no jackets or ties. [Philadelphia Daily News, 2/24/2005; Portland Press Herald, 3/6/2005; CNN, 3/3/2006]
