The Boeing X-20 Dyna Soar was a project for a manned spaceplane, cancelled in 1963 when the first prototype was 40% complete. A lot of the lessons learned on Dyna Soar were applied to later programs such as the Space Shuttle and various maneuverable re-entry vehicle programs. Some good diagrams of several version of the Dyna Soar are available here:

The page doesn't appear to be working for me.

EDIT: It seems to be working now. Looks really good, thanks for posting this.

Good Find! One intresting fact about the X-20 what not everyone knows it that the name Dyna Soar comes from shortening the term Dynamic Soaring. The concept was based on the idea that you could skip a spacecraft on the upper atmosphere using the same basic principle that allows you to skip a flat stone on the surface of a lake. While they never put the concept into practice, the theory is actually quite interesting to read up on.

The basic idea was first seriously proposed by Eugen Sanger for his Antipodal Bomber. The most recent application of it that occurs to me off the top of my head was the "Hypersoar" concept which added the wrinkle of a scramjet that burned during the low "dips" in the trajectory to boost range. But skipping for re-entry is no longer considered a good idea... early on it was thought that it would make re-entry heating less of a problem, as the craft could radiate away the heat during the exoatmospheric upper parts of the trajectory. But it was found that that doesn't work. During the high-heating phases, the structure of the vehicle absorbs heat, and durign the exoatmospheric phase, when it's supposed to be cooling off, the heat is instead diffusing into the interior of the vehicle. Conduction turned out to be far more powerful of a heat transfer mechanism than radiation.
