of them, Khalid al Mihdhar and Majed Moqed, checked in at the American
Airlines ticket counter for Flight 77, bound for Los Angeles.Within the next
20 minutes, they would be followed by Hani Hanjour and two brothers, Nawaf
al Hazmi and Salem al Hazmi.

Hani Hanjour, Khalid al Mihdhar, and Majed Moqed were flagged by
CAPPS.The Hazmi brothers were also selected for extra scrutiny by the air-
line's customer service representative at the check-in counter. He did so
because one of the brothers did not have photo identification nor could he
understand English, and because the agent found both of the passengers to
be suspicious.The only consequence of their selection was that their checked
bags were held off the plane until it was confirmed that they had boarded
the aircraft.

All five hijackers passed through the Main Terminal's west security screen-
ing checkpoint; United Airlines, which was the responsible air carrier, had
contracted out the work to Argenbright Security.
13
The checkpoint featured
closed-circuit television that recorded all passengers, including the hijackers,
as they were screened. At 7:18, Mihdhar and Moqed entered the security
checkpoint.
Mihdhar and Moqed placed their carry-on bags on the belt of the X-ray
machine and proceeded through the first metal detector. Both set off the alarm,
and they were directed to a second metal detector. Mihdhar did not trigger the
alarm and was permitted through the checkpoint. After Moqed set it off, a
screener wanded him. He passed this inspection.

About 20 minutes later, at 7:35, another passenger for Flight 77, Hani Han-
jour, placed two carry-on bags on the X-ray belt in the Main Terminal's west
checkpoint, and proceeded, without alarm, through the metal detector. A short
time later, Nawaf and Salem al Hazmi entered the same checkpoint. Salem al
Hazmi cleared the metal detector and was permitted through; Nawaf al Hazmi
set off the alarms for both the first and second metal detectors and was then
hand-wanded before being passed. In addition, his over-the-shoulder carry-on
bag was swiped by an explosive trace detector and then passed. The video
footage indicates that he was carrying an unidentified item in his back pocket,
clipped to its rim.

When the local civil aviation security office of the Federal Aviation Admin-
istration (FAA) later investigated these security screening operations, the
screeners recalled nothing out of the ordinary.They could not recall that any
of the passengers they screened were CAPPS selectees. We asked a screening
expert to review the videotape of the hand-wanding, and he found the qual-
ity of the screener's work to have been "marginal at best." The screener should
have "resolved" what set off the alarm; and in the case of both Moqed and
Hazmi, it was clear that he did not.

At 7:50, Majed Moqed and Khalid al Mihdhar boarded the flight and were
seated in 12A and 12B in coach. Hani Hanjour, assigned to seat 1B (first class),
