Loss of Separation Reported Between Marine One Carrying Trump and Passenger Aircraft

The required minimum separation was briefly lost between Marine One, carrying U.S. President Donald Trump, and an Envoy Air Embraer E170 operating flight 3742 after departing Ronald Reagan Washington National Airport.

According to Reuters, citing FAA data, the two aircraft came within approximately 0.8 nautical miles horizontally and 700 feet vertically during the incident.

The event occurred on August 4 as Marine One flew from the Ellipse near the White House to Joint Base Andrews. Around one minute after the helicopter departed, the passenger aircraft took off for Pensacola. The two aircraft were not on a collision course and did not come dangerously close.

Air traffic control recordings indicated that some radio transmissions were broken and difficult to understand. Following a traffic advisory from the controller, the Marine One crew briefly entered a holding procedure. Another passenger aircraft on approach also conducted a go-around during the incident.

Marine One and the Envoy Air aircraft completed their flights safely. The FAA and NTSB have launched investigations, while the White House said Trump was not in danger at any stage.

Rules governing helicopter and passenger aircraft operations around Ronald Reagan Washington National Airport were tightened following the January 2025 collision between a passenger aircraft and a military helicopter that killed 67 people.

Under current procedures, commercial aircraft departures and arrivals are required to be suspended while Marine One is operating in the area.
