A three stage vehicle to transport 10 passengers to space stations and the like. I’ve recently come into possession of a whole bunch of reports on the Reusable Aerospace Passenger Transport and Reusable Orbital Transport programs; at some point these might make the makings of an APR article.

The third stage bears a vague similarity to the Boeing Dyna Soar in configuration, but is an entirely different vehicle. This concept helped set the course towards the Space Shuttle.
