Hypersonic Transport Operating Cost May Be Half That of 707
New York—It may pay to move passengers through the atmosphere at Mach 6 to Mach 20. Working from what he believes to be attainable assumptions, Robert A. Cornog of Space Technology Laboratories, Inc., estimates direct costs of hypersonic flight will run 5 cents/ton-mile or, with a load factor of 0.5 and 200 lb./passenger, 1 cent/seat-mile.
