SpaceX has refused to confirm whether the video is the real thing. At a briefing about Friday's planned Falcon 9 launch to send cargo to the International Space Station, the company's vice president of mission assurance, Hans Koenigsmann, again declined to comment on "a video that wasn't produced by SpaceX."

Koenigsmann did confirm that the mishap occurred when the Dragon was on the test stand. The capsule had successfully test-fired its smaller Draco thrusters, but just before it fired its SuperDraco engines, "there was an anomaly and the vehicle was destroyed."
