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.

The incident in which a SpaceX rocket broke up after launch demonstrates the challenges the FAA will face as the number of commercial space flights increases.

"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."
