Lockheed Martin Space Systems Spaceships Design

Lots of pretty pictures.

Of course, the design looks kinda familiar.

You make too much of this.
Given identical physical laws, identical problems, & identical or similar materials & technologies, engineers will tend to produce similar solutions.

There’s only so many ways to streamline something.

Well, it’s better looking than Boeing’s design.

And made something essentially brick-shaped fly.

Please enter your own search for the “Dynasoar” X-20 here. I would put a link but the only one I found with nice pictures brought up a million pop-ups. Maybe the NASA site has something.
