I think it comes down to safety. Supposedly the hybrid is a safer rocket motor than a conventional liquid engine. I understand their concern. They already have 600 tickets sold at $250k a piece and if on launch number 40 the rocket goes BOOM, which liquid rockets are prone to do, it could be a disaster. I think eventually it's a given that one of the rocket motors will explode. Hopefully when the hybrid one goes, say from a air pocket in the solid fuel, it won't be a fatal disaster. That all being said - space is dangerous. I hope people are prepared for all that entails.

Agreed, They might as well close the company when a disaster happens. I wouldn't risk my life for 3 minutes of weightlessness. A week or two in space is another story.

  Yeah I don't like the idea of going to space for a quick trip very much. Rockets are incredibly powerful, and hence dangerous, machines. Never mind all the inherent dangers of the environment. It's just not enough pay off for me. One could always take a lift on the vomit comet if they want to feel weightless: http://en.wikipedia.org/wiki/Reduced_gravity_aircraft http://en.wikipedia.org/wiki/Reduced_gravity_aircraft A trip to the ISS though? Holy cow I'd risk my life to go there. 300km orbit for a few weeks? It's just too much to pass up.

  Of course you are right it would be a complete disaster. However that might not be the end of it all. HN's SimonW gave a talk at Electromagnetic Wave 2013 about the fun and frolics of Zepplins. Apparently plenty of them crashed and burned, but people kept travelling on them. Early aeroplanes would crash too. http://lanyrd.com/2013/emw/scgptt/ http://lanyrd.com/2013/emw/scgptt/

There's very little evidence of their hybrid rocket motor being safer than liquid fueled engines. An accident at the Scaled Composites plant killed 3 people and severely injured several others during a test of the rocket system, for example. Also, liquid rockets are not particularly prone to "go boom", the most likely failure scenario is a loss of control, but that can happen to any rocket.
