A military helicopter carrying US President Donald Trump came dangerously close to a commercial passenger jet over Washington. The air traffic scare happened on Tuesday afternoon during a presidential flight. Marine One came within 0.8 miles (1.2 km) of an Envoy Air regional jet.

Federal safety rules require at least 1.5 miles of horizontal clearance around the airport. The Federal Aviation Administration confirmed a temporary loss of separation.

Radio Miscommunication Led to Air Traffic Delay

The incident began as Marine One prepared to leave the White House Ellipse. The helicopter crew tried three times to alert the control tower before liftoff. Air traffic controllers at Reagan National Airport reported the transmissions were broken and unreadable.

The control tower failed to pause commercial departures as required by protocol. Envoy Air Flight 3742 took off for Pensacola just seconds before Marine One entered the flight corridor. Controllers quickly alerted both aircraft to hold position and diverge.

White House and Marine Corps Defend Flight Operations

The White House reassured the public that President Trump was safe throughout the flight. Official statements emphasized that top military aviators always pilot Marine One.

The US Marine Corps rejected claims of a dangerous close call. Military officials stated the helicopter followed standard flight paths and received no delay orders from the tower. Both aircraft landed safely at their destinations without further incident.

Federal Authorities Launch Investigations Following Past Tragedy

The National Transportation Safety Board launched a formal probe into the airspace breakdown. The FAA convened a safety review team to examine tower audio logs and radar data.

This incident raised immediate concerns due to heightened security in capital airspace. Strict rules were implemented after a fatal mid-air collision near Reagan Airport in January 2025. Investigators will review why air traffic procedures failed to protect presidential airspace.
