On 4 August 2026, Marine One, carrying President Donald Trump, lifted off from the White House Ellipse and climbed toward Ronald Reagan Washington National Airport. While the helicopter was ascending, an Envoy Air Embraer 170 (flight 3742, bound for Pensacola) departed the same airport. A preliminary FAA review found a brief loss of the mandated 2.4 km horizontal and 150 m vertical separation; the aircraft came within less than a mile (about 1.6 km) of each other but were not on a collision trajectory. Both the FAA and the National Transportation Safety Board (NTSB) have opened formal investigations. On 27 August 2026, the NTSB released findings specifying that the aircraft came within 0.82 nautical miles and 700 feet vertically of each other. Investigators identified that ongoing White House construction, including a new ballroom project, created a radio blind spot, as the helicopter’s temporary operating location at the Ellipse lacked a sufficient line of sight to the control tower. Although pilots and controllers had agreed on a backup plan via Joint Base Anacostia-Bolling, that alternative also failed. Because the Embraer aircraft involved is of Brazilian design, Brazil’s aeronautical agency, CENIPA, has been notified of the investigation. Following the incident, the FAA moved the radio receiver to the top of the Reagan National tower to improve connectivity. However, Marine One experienced a separate communication failure with air traffic control on 28 August 2026. While the FAA confirmed contact was established before that takeoff, the recurrence has raised renewed concerns regarding aviation safety and ~~infrastructure~~ air traffic control staffing in the Washington area.
