Investigators Examine Altitude Data in Black Hawk and Passenger Jet Collision

The remains of all 67 victims of last week's midair collision of an American Airlines flight and an Army helicopter near the nation's capital have been recovered, authorities said Tuesday. All but one has been identified.

Meanwhile the NTSB said it was examining new data that could put the helicopter above its 200-foot (61-meter) flight ceiling. The airport's air traffic control screen — relying on radar sensors and other data — had it at 300 feet (91 meters), the agency said. However that figure would have been rounded to the nearest 100 feet, according to authorities. Investigators said they need to get more information from the still-submerged Black Hawk to verify the data.

The jet’s flight recorder showed its altitude as 325 feet (99 meters), plus or minus 25 feet (7.6 meters).

Earlier in the day, crews working in choppy conditions raised a number of large pieces of the jetliner from the Potomac River, including the right wing, the center fuselage and parts of the forward cabin, cockpit, tail cone and rudder.
