I absolutely have. A rocket engine, or air propulsion cannot work in a vacuum. There is zero resistance to push anything forward. It's so crazy. I've seen all of the videos of true vacuums built and propulsion inside that can't even move a flag. Everything NASA(US Defense Dept) tells you dies under the weight of its own details.

It just baffles me how Mr. Pettit stands on a stage to this day and claims they can't solve the "Tyranny of the Rocket Equation", which is how to carry enough fuel for their payloads, and that we can't leave "low earth orbit", and yet here we are going to the moon again. It's astounding.

This.

And they're completely omitting the zero propulsion in space detail.
