The incident occurred as Marine One lifted off from the White House Ellipse while a commercial regional jet departed simultaneously from nearby Reagan National Airport. Approximately 1 minute later, Envoy Air Flight 3742, an Embraer E170 regional jet bound for Pensacola, Florida, took off from Reagan National Airport. SubscribePreliminary findings indicate that the passenger jet passed above the presidential helicopter without entering a converging flight path. Standard security procedures usually require air traffic controllers to halt commercial departures and arrivals at Reagan National Airport while the presidential helicopter is in transit through local airspace. The safety review follows heightened airspace precautions established after a January 2025 collision between an American Airlines regional jet and an Army Black Hawk helicopter near the capital, which led to stricter rules for mixed helicopter and commercial jet traffic around Reagan National Airport.
