Marine One, the helicopter carrying President Trump, came within less than a mile of a commercial passenger jet near Washington's Reagan National Airport on Tuesday, prompting a federal investigation and fresh concerns about air traffic control in the congested area.
The Federal Aviation Administration said the presidential helicopter flew too close to an Envoy Air flight that had just taken off from the airport. Air traffic controllers had failed to pause commercial flights during Marine One's departure, according to sources.
The close encounter raised new worries about airspace safety in the busy Washington area, where commercial traffic and presidential movements often overlap. Officials said they were investigating what happened and how the two aircraft ended up so near each other.
No injuries or damage were reported, and the president was not in danger, but the incident highlighted the challenges of coordinating flights in the region.
