Falcon 9 Major Launch Failure

It was to be the third attempt at landing the first stage on a barge, but it never made it far enough along in the flight in order to attempt it.

I watched the launch, and it looked like it may have blown up at at 2:19 into the flight.  At first, I thought it was the first stage separation, but that would be a bit too soon.

As of this writing, which is about 30 minutes after the flight attempt, there is no word on what exactly went wrong.

Nobody was likely injured, as the launch was unmanned, and the rocket was well downrange when the apparent explosion took place.
