Do they have a self-destruct?
Maybe they lost control of the trajectory & blew it?
The mission’s primary objective was to deliver the Dragon to the space station with more than two and a half tons of supplies, equipment and experiments — ranging from a new docking adapter for accommodating future U.S.-built spaceships to a virtual-reality headset for the station’s crew.
Now that you mention it, the point of ignition did look a bit far from the engine.
Matter of fact it looked something inside the cargo fairing blowed up real good.
Doesn't mean they didn't terminate the flight with the big red button.
I'm thinking third-stage motor, but who knows.
Another notch in the old belt for the ISS occupants.
Looked like explosion inside the cargo fairing, followed by lots of venting from the cargo area, followed by a self-destruct signal that blew the first and second stages.
