(COOLEST AND MOST ADVANCED AIRCRAFTS MADE)Why did it named X-Planes?
The X-planes are a series of experimental United States airplanes and helicopters (and some rockets) used to test and evaluate new technologies and aerodynamic concepts. Common tests have been done at Edward Test Base.
Some of the X-planes have been well publicized, while others, such as the X-16, have been developed in secrecy.The first, the Bell X-1, became well known after it became, in 1947, the first aircraft to break the sound barrier in level flight. Later X-planes supported important research in a multitude of aerodynamic and technical fields, but only the North American X-15 rocket plane of the early 1960s achieved comparable fame to that of the X-1. X-planes 7 through 12 were actually missiles (used to test new types of engines), and some other vehicles were un-piloted (some were remotely flown, some were full-on drones).
Here the list of some of them:
1. Bell X-1
First aircraft to break the sound barrier in level flight.Proved aerodynamic viability of thin wing sections.

Testbed for SM-64 Navajo missile.
3. Bell X-14
The Bell X-14 (Bell Type 68) was an experimental VTOL aircraft flown in the United States in the 1950s. The main objective of the project was to demonstrate horizontal and vertical takeoff, hover, transition to forward flight, and vertical landing. Fold a Bell X-14 stealth plane here.
The North American X-15 was a rocket-powered aircraft operated by the United States Air Force and the National Aeronautics and Space Administration (NASA) as part of the X-plane series of experimental aircraft. 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. As of 2013, the X-15 holds the official world record for the fastest speed ever reached by a manned aircraft. Its maximum speed was 4,520 miles per hour (7,274 km/h)
5. Hiller X-18
The X-18 was an experimental cargo transport aircraft designed to be the first testbed for tiltwing and VSTOL (vertical/short takeoff and landing) technology. Make plane look like this here.
6. Dyna-Sonar X-20
The Boeing X-20 Dyna-Soar ("Dynamic Soarer") was a United States Air Force (USAF) program to develop a spaceplane that could be used for a variety of military missions, including reconnaissance, bombing, space rescue, satellite maintenance, and sabotage of enemy satellites. The program ran from 24 October 1957 to 10 December 1963, cost US$660 million ($5.01 billion today), and was cancelled just after spacecraft construction had begun.

The Northrop X-21A was an experimental aircraft designed to test wings with laminar flow control. It was based on the Douglas WB-66D airframe, with the wing-mounted engines moved to the rear fuselage and making space for air compressors. The aircraft first flew on 18 April 1963 with NASA test pilot Jack Wells at the controls.Although useful testing was accomplished, the extensive maintenance of the intricate laminar-flow system caused the end of the program.
