The FAA grounded SpaceX's Starship pending an investigation into the failure that caused the rocket to break apart midflight after launching on Thursday.

"During the event, the FAA activated a Debris Response Area and briefly slowed aircraft outside the area where space vehicle debris was falling or stopped aircraft at their departure location."

The U.S. Federal Aviation Administration said on Friday it will oversee an investigation by Elon Musk's SpaceX into an explosive Starship test flight the previous day that forced airlines to divert dozens of flights to avoid debris.
