Waking up this morning, I'm reminded of Burt, Dick, and Jeana and their round the world trip. In the beginning, everyone was a 'Burt' financing, fabricating and testing the voyager. Eventually, Dick and Jeana climbed in the Voyager and flew around the world while Burt provided ground support. Even that flight had to deal with technical problems including loss of the wing tips on takeoff yet they pulled it off.

So it isn't an either build or fly choice but first comes the build and then comes the flying. Like any flight, there is no guarantee that new (or old) technology won't have problems but a through understanding gives us choices.
