Airport security?

Two US Airways planes clipped wings while on the ground Saturday morning at Reagan National Airport.

Airline spokesman Morgan Durrant says no one was injured in the incident, which occurred at about 9:30 a.m. However, there was enough damage that Flight 1703 to Fort Lauderdale, Fla., had to be canceled. Durrant says all 143 passengers have been accommodated on other flights.

The other plane was a weekend shuttle arriving from LaGuardia. It had 91 passengers on board.

The same people directing traffic on the runways are responsible for the security of the airfield from incoming unauthorized flights.
