The Federal Aviation Administration says a military helicopter carrying U.S. President Donald Trump, Marine One, was briefly too close to a passenger airplane departing Reagan Washington National Airport on Tuesday. Multiple outlets report that the incident occurred as the commercial plane was cleared to take off while Marine One was nearby, a timing that raised questions about air traffic separation procedures during periods when commercial activity is often paused. According to reporting cited by several sources, Marine One came within less than a mile of the passenger aircraft. The White House says the president was never in danger. The FAA plans an inquiry into what happened, and at least one report indicates U.S. authorities are investigating a reported loss of separation event involving Marine One and the commercial aircraft. Deutsche Welle notes the review relates to safety rules adopted after a deadly January 2025 collision between a military helicopter and a commercial jet that killed 67 people. While outlets differ in emphasis, they agree on the core facts: a near-miss occurred near Reagan National Airport, the FAA is examining separation and communications, and Trump was not at risk.
