Still barking up the wrong tree.

They need to use EM rails up a mountainside to achieve launch velocity without all the extra weight of fuel and tanks.

“They need to use EM rails up a mountainside to achieve launch velocity without all the extra weight of fuel and tanks.”

Seems like a good idea. Also they could use an air-breathing, winged vehicle to get up aways in the atmosphere and get some initial velocity.

Re: “EM rails”

How long would the EM rails have to be so the acceleration won’t harm a human body?

I’m guessing miles?
