XHSP-26 (experimental hypersonic plane)

this is the xhsp-26 a plane based off of the Douglas y-3 but made to go over Mach 5. Made out of 0.5 inches of tungsten steel this aircraft can be able to withstand the pressure and thermal resistance of Mach five speeds. With a power plant of a scramjet engine also accompanied by 2 j79 engines (used on the rs-71) it can become the first manned aircraft to (possibly) reach Mach 5. Also its other counterparts such as the I/F-26 and RS-26-3.(coming soon
