Men detained 3 hours for school materials

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.

...

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

Police officers from the Port Authority of New York and New
Jersey, which operates the airport, took the men into custody soon
after the plane landed around 3:20 p.m., said a Port Authority
spokesman.

After being questioned by authorities, the men were released around 6 p.m., Siegel said.
