This is well after the first and second stage were gone, so I suspect it was something about the pad itself that resulted in the second explosion event. Any ideas?

  • $\begingroup$ No info yet, even SpaceX has said that doesn't know for the moment. You will know after some months from internet websites, it won't be a secret info and very difficult to find, for sure a lot websites will write for this. $\endgroup$

  • $\begingroup$ I believe someone mentioned on /r/SpaceX that it was an RP-1 tank on the pad; don't have sources, though. $\endgroup$

  • $\begingroup$ @DylanSp I suspected as much as well, but I haven't seen it mentioned at all really, except for briefly in this video. I don't know what else could have caused this to happen, however, it's not like they keep explosive things near a launch pad that don't need to be there! $\endgroup$

A firefighter on the scene reported that a number of train rail cars, and ground support tanks were burned and blew up in the process. Could be one of any of those.

    $\begingroup$ I would suspect the latter, but what is meant by a "ground support tank"? $\endgroup$
