“What you need is something like a Saturn V, that could put a large mass onto escape velocity. But we haven’t had one of those since 1973.”
IIRC they don’t even have all of the plans for the Saturn V, and wouldn’t know how to build one even if they wanted to. Sad.
Hey, folks. Don't worry about it. This stuff isn't rocket science or anything ... oh. wait. it is.
Never mind.
