Boeing Hypersonic Vehicle Concept
Boeing has been researching hypersonic vehicles for six decades now. Although it's not ready to take off just yet, this Hypersonic Vehicle Concept provides a glimpse of a future that could arrive in as little as 20 years. Capable of traveling Mach 5, it would rely on a turbofan engine at takeoff, switching to a ramjet at altitudes as high as 95,000 feet. As a result, it could make the trip from New York to Tokyo in around two hours, making our already small world that much smaller.
