I am, and of course it is concerning - the engine shut down and debris was strewn about. Do the math on the failure rates. Unless things are dramatically improved (the goal of course), these things are just not safe for people outside of the dare-devil set. That's not a knock against Space X - this is hard stuff. It is a slight knock against Musk's over-the-top marketing that has us on Mars in 15 years, which, in my opinion, is unrealistic.
