The Federal Aviation Administration (FAA) on Wednesday ordered
to ground both the Boeing 737 Max 8 and 737 Max 9 models "as a result of the data gathering process and new evidence collected at the site and analyzed.
The grounding will remain in effect pending further investigation, including examination of information from the aircraft's flight data recorders and cockpit voice recorders," the FAA said.
President Trump earlier Wednesday said the FAA planned to announce that the jetliners would be "grounded upon landing" at their destinations. He said that both pilots and airlines have been notified.
"Any plane currently in the air will go to its destination and thereafter be grounded until further notice," Trump told reporters. "The safety of the American people, and all people, is our paramount concern."
