Recovery crews and divers searched the Potomac River for remains and cleared wreckage Saturday from the midair collision of a passenger jet and Army helicopter that killed 67 people. A Coast Guard cutter outfitted with a crane waited by the wreckage as occasional recovery team members slipped into the water amid a group of smaller emergency boats. No one survived the Wednesday night collision. The remains of 42 people had been pulled from the river by Saturday afternoon, including 38 that had been positively identified, according to Washington emergency officials. They expect to recover all of the remains, though the wreckage of the plane's fuselage will probably have to be pulled from the water to get all the bodies, officials said. On Friday night the helicopter “was briefly stabilized with a crane to assist in recovery efforts, however, it has not been removed from the water,” the Washington Fire and EMS Department said in the Saturday statement. The collision occurred as an American Airlines flight from Wichita, Kansas carrying 64 passengers was preparing to land at Ronald Reagan National Airport, just across the Potomac from the nation's capital, and hit an Army Black Hawk helicopter that apparently flew into the jet's path. The helicopter had three soldiers on board. Army officials have said the helicopter crew was highly experienced, and familiar with the congested skies around the city. Military aircraft frequently make such flights to practice routes they would use if key government officials need to be evacuated during an attack or major catastrophe. The National Transportation Safety Board is scheduled to update reporters on Saturday evening. Investigators are examining the actions of the military pilot and air traffic control. Full NTSB investigations typically take at least a year, though investigators hope to have a preliminary report within 30 days. Other possible factors in the crash, including the helicopter’s altitude and whether the crew was using night vision goggles, are still under investigation, Defense Secretary Pete Hegseth told Fox News Channel. Black boxes have been recovered from both aircraft.
