"I've come across more and more people who've actually tried reading science fiction and can't make it make sense."
The Nautilus, a passenger spacecraft, was in orbit around Venus. What was the best way for a passenger like Don Harvey to get to the surface?
And how could such a ship find its way safely back to a designated landing site on the surface of the planet? By using, as Heinlein points out, the energy it had already built up in gaining orbit:
(Space Shuttle Columbia)
Note that in Heinlein's "design" the shuttle ship uses a catapult to reach ramjet speed; rocket engines are used only in the last part of the launch. The actual Space Shuttle uses a large external fuel tank with solid fuel boosters to reach orbit.
Thanks to Larry for pointing this one out, and supplying the references.
