Planes can float, but the US Airways Airbus A320 that crashed into the Hudson River yesterday had a better chance than most. That's because it was equipped with a special device unique to Airbus planes that increased the likelihood it would stay on top of the water. The device, called a "ditching switch," effectively seals the plane by closing valves and ventilation ports, a spokesman for the airline said.

With the valves and ports shut, "a float line" is created, Airbus spokeswoman Mary Anne Greczyn said.
