The history of hyperplanes begins with the development of X planes. The rocket powered Bell X1 flown in 1947 by Chuck Yeager was the first plane to fly faster than sound. This was the beginning of supersonic era of flights.

In 1960’s during cold war America developed XB-7O Valkyrie(Mach-3.08) to be used instead of ICBM’s . It was conceived in the 1960s as a strategic bomber that could deliver nuclear weapons. It holds the record for being the largest Experimental plane ever. It could fly at Mach 3.08 and achieve an altitude of 74,000 ft. Ultimately; it was only put to use as a research aircraft. It was simply too impractical when compared to an Inter-Continental ballistic Missile ( ICBM ).

At the same time during cold war time Soviets developed a plane similar to XB-70 , it is Su T4. The T-4, also called S100 (indicating that it was a prototype) first flew in 1972 and easily achieved Mach 1.28 at 12,000m. The aircraft completed a number of successful flight tests and showed a real promise of reaching its design requirements. The T-4 featured world's most advanced electrohydraulic, quadruple redundancy fly-by-wire system. When the nose of the aircraft was up and locked, the pilots had no forward visibility and all flying was on instruments.


The North American X-15 rocket-powered aircraft was part of the X-series of experimental aircraft, initiated with the Bell X-1, that were made for the USAF, the NASA, and the USN. The X-15 set speed and altitude records in the early 1960s, reaching the edge of outer space and returning with valuable data used in aircraft and spacecraft design. The record of Mach-6.7 was set by Pete Knight in the rocket powered X-15 in 1967.
