"The sleek aircraft would cruise at Mach 5 (3,350 mph) speed at a maximum altitude of about 100,000 feet. The aircraft would be made primarily of titanium with its outer edges constructed of Inconel, a heat-resistant stainless steel. At Mach 5 speed the leading edges of the air-frame would glow red above 1,000 degrees Fahrenheit. Power for this futuristic airplane would come from four turbo-ramjets. The engines would operate as turbojets at low speeds, but at higher speeds the compressor and turbine would be overridden so the engines would operate as ramjets."
