    Well done!
  1.  
    Now we know we can do it, let's get some video from inside those holes!

    Inside holes!? Have you ever tried to control one of those things?
  2.  
    I know you have. But have you seen the size of some of those holes? And the control is Full Self Driving anyway. None of that shaky human stuff.

    I'm not sure if it has an obstacle avoidance sonar. I wonder how air pressure would alter the capability of that.


    ETA likely not

    All very impressive nonetheless!

    My design is significantly better. It's based on the fact that adding extra BHs to the drive with carefully selected masses (hence lifetimes) results in faster trip times. But the damn equations are so highly nonlinear that I could not find a closed form solution, so selecting the correct set of masses is left to a nonlinear solver (I used Solver from Excel 2003, which was free). Tip o' the hat to Crane & Westmoreland for a rocketing nutso foundational paper. It's on arXiv btw.

    Would "languishing" be the correct way to designate Skylon?
