Another SpaceX rocket in fiery end

WASHINGTON－Third time's a charm? Not so for SpaceX, whose unmanned rocket exploded on the ground on Wednesday after carrying out what had seemed to be a successful flight and landing－fresh on the heels of two fiery crashes.

It was yet another flub involving a prototype of the Starship rocket, which SpaceX hopes one day to send to Mars.

"A beautiful soft landing," a SpaceX commentator said on a live broadcast of the test flight, although flames were coming out at the bottom and crews were trying to put them out.
