SpaceX Launch Failure

SpaceX's third launch attempt has failed. It looks like the first stage did not separate prior to second stage ignition. As you would expect, that makes for a bad day. I did get a chuckle from the "doubts about private space flight" comment. How many launch failures did NASA have before reaching orbit? This is only SpaceX's third launch attempt. A more relevant question might be how many people has SpaceX killed vs. how many people NASA has killed. But that would probably be considered impolite.
