Video shows 9/11 hijackers' security check
Nawaf and his brother, each wearing slacks and Oxford shirts, were directed to a nearby counter, where they appeared to examine their tickets while another screener checked Nawaf's carryon bag with an explosive trace detector. Each was cleared to board Flight 77.
The Associated Press obtained the video from the Motley Rice law firm, which is representing some survivors' families who are suing the airlines and security industry over their actions in the Sept. 11 attacks.
"Even after setting off these alarms, the airlines and security screeners failed to examine the hijackers' baggage, as required by federal regulations and industry mandated standards, or discover the weapons they would use in their attack," lawyer Ron Motley said.
