In early August 2026 Marine One lifted off from the White House and briefly lost separation from Envoy Air flight 3742, an Embraer 170 departing Ronald Reagan National Airport. A preliminary FAA review confirmed a momentary near‑miss; both aircraft continued away from each other while controllers remained in contact. The FAA and NTSB opened formal investigations into whether the post‑January 2025 departure‑hold rules—requiring commercial flights to be halted and enforcing a minimum 1.5‑nautical‑mile horizontal and 500‑ft vertical separation—were followed. Controllers did not pause the commercial departure, prompting questions about protocol compliance. A second commercial flight, Republic 4700, was rerouted as a precaution. Both agencies later concluded the aircraft were not in dangerous proximity and the President faced no risk, while the White House emphasized the skill of Marine One pilots.

Further details released on 4 August 2026 indicated the helicopter passed within about one mile (1.6 km) of the commercial jet, below the mandated 1.5‑mile horizontal separation. The FAA reiterated that the incident was not dangerous and said it was reviewing safety measures. The episode resurfaced scrutiny of Washington’s congested airspace and coincided with a pattern of aggressive, then retracted, threats by President Trump toward Iran, raising broader U.S. security concerns.
