NASA X-43 has a top speed of 7,310 miles per hour! The hypersonic aircraft was developed by NASA as part of their new Hyper-X program and is designed to resemble the Pegasus Rocket. The experimental jet is the fastest in human history and is being carefully tested by the government.
3 prototypes of the NASA X-43 were made and the first one, was intentionally destroyed after it experienced a mid-flight malfunction. The final 2 prototypes successfully reached a speed of 7,310 miles per hour but then, were crashed into the ocean.
