Student put box cutters on planes 'five weeks ago'

A college student told US authorities he placed box cutters and other banned items aboard two Southwest Airlines planes nearly five weeks before they were found, according to an FBI affidavit.

The affidavit said Nathaniel Heatwole, 20, told agents he went through normal security procedures at airports in Baltimore and Raleigh-Durham, North Carolina, and was able to carry the forbidden items on to the planes.
