A jet with 60 passengers and four crew members aboard collided Wednesday with an Army helicopter while landing at Ronald Reagan National Airport near Washington, prompting a large search-and-rescue

The U.S. Army described the helicopter as a UH-60 Blackhawk based at Fort Belvoir in Virginia. The helicopter was on a training flight. Military aircraft frequently conduct training flights in and around the congested and heavily-restricted airspace around the nation’s capital for familiarization and continuity of government planning.
