Paraphrase of Musk's tweet, rockets are tricky. And indeed, it wasn't a mission launch, just as someone else would say the rocket failure the other day was not a manned mission, and today's Virgin Galactic is also a test..

There's a reason why we've set a category of difficulty in common language calling it 'rocket science.'

OMG...The Antares vehicle from contractor Orbital Sciences Corp was a mission failure. It was a mission launch...

Not a test....lol. Test are conducted to see if things are right for actual missions...It's why they test them first, and it's still no guarantee, but it really helps to ensure successful missions. No?

Another wild guess, but I think that's what testing these vehicles are all about.

Are some of you folks working in call centers for Dial an Argument?
