The first space shuttle was made by the National Advisory Committee for Aeronautics, or NACA, and the United States military after getting the idea from the Silbervogel proposal. The Silbervogel proposal was part of a German project intended to create an aircraft that could bomb the U.S.
In the 1930s, Germany started the "Amerika Bomber" project. Along with this project, one engineer, Eugen Sanger, submitted a proposal called "Silbervogel." Germans never completed the project, and after World War II, the Silbervogel idea found its way into U.S. hands during Operation Paperclip. The Bureau of Aeronautics started pursuing the concept and involved the NACA, which was the precursor to NASA, and the U.S. military in the project. This led to the manufacturing of the X-15 rocket plane.Learn More

In response to a request from the United States Department of Defense, work began on a system that would enable computers to connect and share information between universities. The first successful connection between two locations was achieved in 1969 through a system called ARPAnet, often written as ARPANET, and is considered to be the predecessor of the modern Internet. The actual start of the U.S. government-supported development of the protocols and packet-switched systems required to share information across research centers began as early as 1962 and was in response to the first successful launch of an orbiting satellite, Sputnik, by the Soviet Union in 1957.Full Answer >
