Safety in the sky: new restrctions (PART 1)

Tougher airline security measures were imposed Friday after a man flying from Nigeria to Amsterdam then to the U.S. on a Northwest Airlines flight tried to ignite an explosive as the plane prepared to land in Detroit. On Sunday, police met another Amsterdam-to-Detroit flight after the crew reported a "verbally disruptive passenger." A law enforcement official said the man posed no security risk to the plane.

Government officials have refused to discuss what restrictions had been put into place, but in many airports lines were longer and security personnel were extra diligent.

Travelers on incoming international flights said that during the final hour, attendants removed blankets, banned opening overhead bins, and told passengers to stay in their seats with their hands in plain sight.
