Elon Musk's enthusiasm for and confidence in his private space-launch venture seems to exceed the technical mastery of the engineers working on his Falcon 1 launcher. Musk described the third launch of Falcon 1, carrying three NASA and DoD satellites, as "picture perfect".
That would be "picture perfect" except for the part where the first and second stages failed to separate, with the resulting loss of the entire vehicle and payload.
This puts the Falcon at 0 for 3. If I were in Musk's position, I think I might seriously consider doing my test launches with dummy payloads until I'd had at least one successful launch, thus avoiding building up an unenviable reputation for destroying my customers' payloads. Let's face it, just about anyone can throw together a booster that doesn't work.
