From an AP story by Marcia Dunn headlined “SpaceX giant rocket explodes minutes after launch from Texas”:

SOUTH PADRE ISLAND, Texas — SpaceX’s giant new rocket exploded minutes after blasting off on its first test flight Thursday and crashed into the Gulf of Mexico.

Elon Musk’s company was aiming to send the nearly 400-foot (120-meter) Starship rocket on a round-the-world trip from the southern tip of Texas, near the Mexican border. It carried no people or satellites.
