NTSB weighs lessons from Hudson River ditching

The National Transportation Safety Board meets today to consider safety lessons from last year's ditching of US Airways Flight 1549 into the Hudson River.

Among the questions: Should airliners be tough enough to withstand collisions with big birds? What about an unexpected plunge into a river?

The plane collided with a flock of Canada geese shortly after takeoff from New York's LaGuardia Airport. The flight's captain, Chesley "Sully" Sullenberger, made a split-second decision to glide the Airbus A320 into the river rather than risk crashing in a densely populated area by trying to reach an airport.

All 155 passengers and crew managed to escape the sinking aircraft.
