CAPE CANAVERAL, Fla. (AP) — The Federal Aviation Administration is demanding an accident investigation into this week’s out-of-control Starship flight by SpaceX.

SpaceX's Starship rocket roared into space from Texas on Tuesday but spun out of control about halfway through its flight without achieving some of its most important testing goals, bringing fresh engineering hurdles to CEO Elon Musk's increasingly turbulent Mars rocket program.

SpaceX has made several hardware changes and improvements to the rocket since its last test flight, which was foiled by an engine anomaly.
