Altitude Confusion Cited in Deadly D.C. Airspace Collision

Investigators revealed new evidence suggesting Army pilots in a Black Hawk helicopter might have misjudged their altitude, potentially contributing to a midair collision with an American Airlines passenger jet near Reagan National Airport in January. This revelation came during the National Transportation Safety Board's public hearings into the crash, which tragically killed all 67 people on board both aircraft. The accident, the first of its kind, highlights the complex and potentially hazardous nature of D.C. airspace.
