In 1949 Tsien Hsue-shen, the leading expert in high-speed aerodynamics working in America, applied the knowledge learned from German rocket developments to the design of a practical intercontinental rocket transport. He proposed a 5,000 km single stage winged rocket clearly derived from V-2 aerodynamics. The 22,000 kg rocket would carry ten passengers from New York to Los Angeles in 45 minutes. It would take off vertically, with the rocket burning out after 60 seconds at 14,740 kph at 160 km altitude. After a coast to 500 km, it would re-enter the atmosphere and enter a long glide at 43 km altitude. Landing speed was to be 240 kph. Tsien�s fundamental theoretical work on this concept lead to him being called the �Father of the Dyna-soar� (a 1950�s/1960�s delta winged spaceplane that was the ancestor of the space shuttle).
