The Marine One Incident Over Washington DC Revealed A Critical Gap In The FAA's Post-Collision Helicopter Rule

Marine One, carrying President Donald Trump, briefly shared airspace over the Potomac River with Envoy Air Flight 3742 near Washington National Airport (DCA) on Aug. 4, 2026—despite new FAA procedures meant to prevent commercial aircraft from operating near the presidential helicopter. FAA and NTSB information cited in the investigation indicates the aircraft never came close enough to collide and the president was never in danger, but regulators opened a formal investigation and a Safety Review Team. The article says a mandatory ground stop for commercial traffic was not activated before the Envoy departure, even though post-collision rules require a commercial halt while Marine One is active. The case traces back to the Jan. 29, 2025 midair collision that killed 67 people.
