SpaceX’s Crew Dragon suffers catastrophic explosion during static fire test

The April 20th event is the first time in the known history of SpaceX’s orbital spacecraft program that a vehicle – in this case, the first completed and flight-proven Crew Dragon capsule – has suffered a total failure. Regardless of the accident investigation’s ultimate conclusions, the road ahead of Crew Dragon’s first crewed test flight has become far more arduous.

Here’s video showing the explosion:
