The US has grounded SpaceX's giant Starship rocket while an investigation is carried out into why it exploded during its latest test flight. The rocket's upper stage dramatically broke up and disintegrated over the Caribbean after launching from Texas on Thursday, forcing airline flights to alter course to avoid falling debris.

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.
