Wondering how a rocket will go through an oval at extremely high speed. Does the rocket bend?
I suppose it wouldn't have to bend if it was supported along its length inside a cradle, it would just be crushed against the cradle. If the rocket was strong enough, that could work.
I see they plan to spin inside a huge vacuum chamber. That almost eliminates the bird problem, but the release must be timed with incredible precision.
They open the exit port just before releasing the rocket. Air floods in, the spin slows down slightly, then release. All they need is a slight elevation of the spinning mechanism on the release port side. Fins on the rocket can handle the rest.
Hmm.
