According to the ‘official’ version of events…
At 5:33 on the morning of September 11th 2001, lead hijacker, Mohamed Atta, and his co-conspirator, Abdulaziz al-Omari, checked out of room 232 of the
Comfort Inn in Portland, Maine. Their operation, two and a half years in the planning, had entered its final phase.
They placed their baggage into their rented Nissan Altima and drove to Portland International Jetport, arriving at around 5:45. This gave them just
enough time to catch the 6:00 commuter flight to Boston’s Logan airport, from where they would later board the 7:45 departure, Flight 11, to Los
Angeles.
This connecting flight to Boston was the last leg of a rather circuitous journey for Atta, which saw him fly from Baltimore to Boston on the 9th, and
having collected Omari, drive from Boston to Portland on the 10th. There appears to have been no good reason for the two men to have left Boston, and
their decision to do so exposed them to potential delays that could have jeopardised their participation in the mission.
Having arrived at the airport, Atta tried to check two items of baggage onto the 19-seat commuter flight to Boston. According to the
9/11 Commission Report, he…
…was selected by a computerized prescreening system known as CAPPS (Computer Assisted Passenger Prescreening System), created to identify
passengers who should be subject to special security measures. Under security rules in place at the time, the only consequence of Atta's selection by
CAPPS was that his checked bags were held off the plane until it was confirmed that he had boarded the aircraft.
These measures, designed to establish that selectees with a high terrorism ‘risk score’ were not carrying explosives, ‘reflected the FAA’s
view that non-suicide bombing was the most substantial risk to domestic aircraft.’
As the events unfolded, Atta’s bags remained in Boston’s Logan Airport; they hadn’t made it on to Flight 11. They were discovered later that day
and conveniently found to contain what former FBI agent Warren Flagg described as ‘the Rosetta stone of the investigation’.
FBI agent James K Lechner lists the bags' contents in an
affidavit filed on September 12th. They included:
numerous documents, including a letter of recommendation and education-related documentation, bearing the names “Mohamed Mohamed Elamir Awad
Elsayed” and “Mohamed Mohamed Elamir Awad Elsayed Atta”; a hand-held electronic flight computer; a simulator procedures manual for Boeing 757
and 767 aircraft; two videotapes relating to “air tours” of the Boeing 757 and 747 aircraft; a slide-rule flight calculator; a copy of the
Koran.
One of the documents found was described by
Bob Woodward of the Washington Post as
‘a cross between a chilling spiritual exhortation aimed at the hijackers and an operational mission checklist’. In it, the hijackers were reminded
to bring ‘knives, your will, IDs, your passport… [and] to make sure that nobody is following you.’ Remarkably, ‘[t]he FBI found another copy
of essentially the same document in the wreckage of United Flight 93… [which] suggest[s] the document was shared among at least some of the
hijackers.’
Less widely reported, is the equally remarkable
claim made by both Flagg and an
unnamed former federal prosecutor that the second bag contained the identities of all 19 hijackers.
