What is the world's fastest plane?

Answer 1

The NASA X-43A is the fastest unmanned rocket/scramjet plane. It cannot initiate flight on it's own. It is launched from under the wing of another aircraft.

The X-15 is the fastest manned rocket plane. It also was launched from under the wing of another aircraft. It's top speed was Mach 6.7

The SR-71 is the fastest jet engine, manned plane. It was capable of sustained Mach 3+ flight and set several official speed records that still stand today.

According to the NASA web site:

"Guinness World Records recognized NASA's X-43A scramjet with a new world speed record for a jet-powered aircraft - Mach 9.6, or nearly 7,000 mph. The X-43A set the new mark and broke its own world record on its third and final flight on Nov. 16, 2004. "

"In March 2004, the X-43A set the previous record of Mach 6.8 (nearly 5,000 mph). The fastest air-breathing, manned vehicle, the U.S. Air Force SR-71, achieved slightly more than Mach 3.2."

While there are other aircraft that claim to be faster than the SR-71, none can sustain Mach 3+. The Russian MIG-25 can only hit a peak of around 3.2 before having to decelerate to prevent severe damage to it's engines.
