In the late 1980s, the U.S. government and the aerospace industry promoted an idea for an airplane that would travel at hypersonic speeds, thus dramatically shortening the time to fly from the United States to the Far East. The concept was officially called the "National Aerospace Plane," also known by the popular name "Orient Express."
This model represents a concept developed by McDonnell Douglas, with Northwest Airlines as a potential customer.
