Preliminary Design of an Experimental World-Circling Spaceship
https://en.wikipedia.org/wiki/Preliminary_Design_of_an_Experimental_World-Circling_Spaceship

The Preliminary Design of an Experimental World-Circling Spaceship was a 1946 proposal by Project RAND for a United States satellite program. Robert M. Salter, Jack Lipp and one other person at RAND served as the editors of the report.[1]

The Preliminary Design of an Experimental World-Circling Spaceship states, "A satellite vehicle with appropriate instrumentation can be expected to be one of the most potent scientific tools of the Twentieth Century. The achievement of a satellite craft would produce repercussions comparable to the explosion of the atomic bomb..."

PROJECT 1947: The RAND World-Circling Spaceship

RAND's advanced rocket engineering concepts were attractive to Project SIGN, the Air Force's UFO analysis activity at Wright Field, which by the middle of 1948 was leaning toward the idea that some "flying disc" reports might represent actual extraterrestrial spacecraft. On July 21, 1948, evidently based on the interests of Maj Gen Charles Cabell, Director of Intelligence, Air Corps [sic] Letter 80-10 requested RAND to "present information that would serve to evaluate the remote possibility that some of the observed objects may be space ships or satellite vehicles." RAND's James Lipp began to consider propulsion technology for UFOs based on extrapolations of the work done on the World-Circling Spaceship study.
