Bell X-2 Starbuster

The Bell X-2, also known as the Starbuster. This is a research aircraft, as opposed to the other aircrafts on our list. Nonetheless, it deserves to be counted among the world's fastest aircraft. Its goal was to investigate the effects of flying at Mach 2-3.

It was ahead of its time when it was created in 1945. It used a rocket engine. Its goal is to investigate common aerodynamic heating problems that may occur during high-speed flights. This aircraft was not created in a short period of time. Instead, it took some time due to the need for temperature resistant materials and technology that could meet the requirements of this specific aircraft.

The X-2 is regarded as a pioneer on numerous fronts. In particular during those years, it has expanded the potential for manned flight. It is also the first airplane manufactured in the US to use a rocket engine.

Only two Bell X-2s have ever been produced. But while it was in operation, it gave scientists the information they needed to create the aircrafts we use today. In actuality, the aircraft's stability and control were the main issues they had to deal with as they got closer to Mach 3.
