Crews worked Tuesday to try to recover the plane's cockpit and the rest of the remains of the 67 people who died in the midair collision between a passenger jet and Army helicopter near the nation's capital last week.
They say their work might depend upon the wind and tidal conditions in the Potomac River, where the aircraft crashed last Wednesday night after colliding as the American Airlines flight was about to land at nearby Ronald Reagan National Airport. All 67 people on both aircraft were killed.
