SpaceX: Leaky valve caused crew capsule to explode in test

CAPE CANAVERAL, Fla. (AP) — SpaceX says a leaky valve caused its crew capsule to explode during a test back in April.
The company announced the preliminary results of its accident investigation Monday.
SpaceX’s crew Dragon capsule had just returned from a successful test flight to the International Space Station and was undergoing a ground test at Cape Canaveral, Florida. The abort-system thrusters were milliseconds away from firing, when the spacecraft exploded and was destroyed.
