Spectators watch the final fiery moments of the Starship test flight

Two days after becoming the first U.S. space fliers to splash down in the sea in more than 45 years, astronauts Doug Hurley and Bob Behnken on Tuesday described their fiery ride back to Earth aboard SpaceX’s Crew Dragon capsule to cap a “flawless” test flight, setting the stage for operational flights beginning later this year.
