TSA sticks to new plan allowing small knives on planes

The head of the Transportation Security Administration says the agency is moving forward with plans to allow small knives on planes, despite the fierce opposition by flight attendants and some passengers.

The TSA's own figures show it's personnel confiscate 2,000 knives a day at the nation's airports.

Knife lobbyists are hailing the decision, but flight attendants say it's a bad idea. The fight is expected to move to Capitol Hill.

In a letter to Congress, TSA Administrator John Pistole defends the plan, writing, "Small pocket knives and certain sporting equipment do not pose a security risk that would result in the catastrophic failure of an aircraft and the loss of all life on board."
