You can see in the GIF above that the rocket touched down on the barge's
landing surface at about 45 degrees to the horizontal. That was because the
fins on the side of the rocket lost power, causing it to drift over to one
side. As it fell towards the barge, the angle of approach meant the legs and
then the engine sections smashed.
From there, residual fuel and oxygen left in the craft were able to combine
and—BOOM—a rather dramatic explosion followed. Or, as Elon Musk puts it,
there was a "Full RUD"—a "rapid unscheduled disassembly" event.
According to Musk, the barge is undergoing some minor repairs. But,
typically, he referred to it as an "Exciting day!" Sure was, Elon. Sure was.
Still, onward and upwards, eh—preferably this time in a straight line.
