Washington: It's not clear why a plane was allowed to take off as President Donald Trump’s helicopter was approaching Ronald Reagan Washington National Airport on Tuesday afternoon in an apparent violation of safety procedures put in place after last year’s midair collision near the busy airport.
Both the National Transportation Safety Board and the Federal Aviation Administration said Wednesday they were investigating what happened when a commercial jet took off just as Marine One left the White House for Andrews Air Force Base with the president aboard for the first leg of a West Coast trip.
