Preliminary data from the deadliest U.S. aviation accident in nearly 25 years showed conflicting readings about the altitudes of an airliner and Army helicopter when they collided near Washington.
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.
In audio from the air traffic control tower around the time of the crash, a controller is heard asking the helicopter, "PAT25 do you have the CRJ in sight," in reference to the passenger aircraft.
