Re: Another mighty initial thrust idea
To Summarise then:
1. A rod/rail launch may or may not produce a straight line launch from a free swinging platform
2. A rod/rail launch may or may not actually slide due to static friction vs small inertial forces
3. A rocket-plane may or may not require giro-stabalisation due to out of line forces
4. No one really reads the detail and meaning of the other posts.
I back iamanidiot: The arguing phase is over and proof is required. Either hard maths or testing.
