Washington air traffic controllers and Marine One pilots met about radio communication problems a week before the 4 August close call at Ronald Reagan Washington National Airport, according to the National Transportation Safety Board’s preliminary findings. The incident involved Marine One carrying President Donald Trump and a departing passenger jet, raising fresh questions over separation procedures around one of the US capital’s busiest airports.
The preliminary report indicates the Marine One crew tried to deliver the required three-minute departure notice, but communications problems interfered. A fallback method agreed in the earlier meeting also failed on the day of the incident, leaving controllers without the expected warning before the helicopter lifted off. The episode unfolded despite post-2025 safety procedures that normally halt commercial traffic when a helicopter is on a conflicting route.
The airspace around Reagan National has been under intense scrutiny since the fatal January 2025 mid-air collision near the airport, which prompted tighter operating rules for helicopters and commercial flights. The new findings suggest those safeguards still depend heavily on reliable radio contact between military crews and civilian controllers, and that the breakdown in communication remained unresolved even after the pre-incident meeting.
