Re: SpinLaunch
When they launch their projectile they suddenly have a centrifuge which is now hugely out of balance, suddenly running in air, with the ends of the arms moving at some significant fraction of orbital speed. This will not end well I think. Could deal with the balance problem by releasing a projectile in opposite direction, but then they must deal with the abrupt release of entire kinetic energy of that projectile when it hits whatever it hits. Which, also, will not end well.
