Men detained 3 hours for school materials

"NEWARK, New Jersey (AP) -- Five airline passengers speaking in foreign languages and carrying "aircraft flight materials" were briefly detained Saturday until authorities determined they were simply returning to their home countries after attending a U.S. helicopter training school.

"Fellow passengers on American Airlines Flight 1874, which had departed from Dallas Fort Worth International Airport, became suspicious of the men, said Steven Siegel, a spokesman for the FBI's Newark office.

"A federal marshal on the plane notified authorities at Newark Liberty International Airport about the men's behavior. (Watch as a passenger describes what happened during the flight -- 1:44)

"The men -- identified only as four Angolan military personnel and an Israeli -- had attended helicopter training school in Texas, Siegel said."
