no kidding
was it carrying something else capable of exploding?
I was going to post this ‘Orbital’s Soviet Rocket Engines Had Already Been Slated for Retirement” http://www.businessweek.com/articles/2014-10-29/orbital-antares-had-soviet-rocket-engines-slated-for-retirement
but I think FR guidelines say that publication is a no-go.
Plus, I suppose somebody could detonate a rocket like Antares if they put a tracer round through it — but we’d need to hear form the FRengineer FRexperts on that.
Like, say, a tank full of rocket fuel and/or oxidizer or the connecting piping, valves, regulators, fittings, etc.?

I haven't seen closeups of the video but another cause could be a fuel tank leak. Start dumping a few hundred gallons of hydrogen or oxygen onto the outside of a hot engine and you could have an explosion that's not the engine's fault.
