PoliticsMarine One incident: Ex-air traffic controller points out ‘no-no’

The Federal Aviation Administration and National Transportation Safety Board are investigating why a passenger-filled commercial jet came too close to the military helicopter carrying President Donald Trump. Marine One departed the Ellipse, just south of the White House, on Tuesday afternoon. Air traffic at nearby Ronald Reagan Washington National Airport continued for several minutes afterward, according to a CNN review of air-traffic data. The incident has raised questions about how the aircraft were managed during the departure.
