An unusual incident occurred during the takeoff of United States President Donald Trump's helicopter from the White House, after a passenger plane was allowed to take off at the same time from Reagan Airport - contrary to safety procedures used during the movement of the presidential helicopter.
The president's life was not in danger.
The Federal Aviation Administration (FAA) has opened an investigation.
Sources familiar with the details told the Wall Street Journal that air traffic controllers did not stop civilian aircraft traffic at Reagan Airport during the presidential helicopter's takeoff, as is customary.
According to the FAA, the Marine One helicopter took off for Andrews Air Force Base, from where Trump continued on Air Force One for a visit to California. At the same time, a passenger plane also took off from Reagan National Airport, near the White House, on its way to Pensacola, Florida.
According to the initial inspection findings, the passenger plane passed over the presidential helicopter, but there was no danger of collision.
The air traffic controller was in continuous contact with both pilots throughout the incident.
