    controlled vanes. The vanes were extensions of the four tail fins. They were hard pressed graphite, which would withstand the heat and pressures in the rocket exhaust long enough to get the thing up to speed and trajectory.  If any of the electromechanical parts was having a bad day, the thing would wander off course. However, our own early experiences with rocket testing did not fare much better.

    This is interesting. The Rutan team are geniuses who think outside the box, much like Kelly Johnson did at the Lockheed Skunk Works.

    •  Rutan et al aren't involved in SpaceX. (2+ / 0-)

      They're with Virgin Galactic and Stratolaunch, the former of which is increasingly starting to look like a PR con by Sir Richard Branson/Scamson, and the latter appears to have limited market prospects.  But the "feather" mechanism on SpaceShipTwo to control reentry is an engineering achievement.

        associated with Elon Musk and Space X on some projects. Thought this was one of them. I have not paid much attention to the rocketry side the past couple of years. I am an airplane guy, so have missed a lot of the politics and intrigue.

          to design the orbital stage for the Stratolaunch air-launched system, but SpaceX dropped out due to market conflicts and limited prospects for the system so they went with Orbital Sciences.  And Allen worked with Rutan on SpaceShipOne, but as far as I know, there have never been collaborations between Rutan and SpaceX.  Wouldn't call it "intrigue" exactly: Stratolaunch always seemed like kind of a marginal proposition that was only exciting while SpaceX was just one of many entrepreneurial companies.  Now that they're THE company and succeeding wildly at reducing launch costs, the air-launch concept is starting to seem moot.
