The U-2 is a very unique aircraft. First flown in August 1955, it is a single engine jet that is designed to fly at altitudes of 70,000 feet.
Basically, the U-2 spy plane is a powered glider and does not have a traditional tricycle style landing gear. Instead, the surveillance aircraft utilizes a bicycle configuration with two sets of wheels, one in front of the other. This setup can make for some very interesting landings for Dragon Lady pilots!
The U-2 is still in service with the US Air Force and was previously flown by the Central Intelligence Agency (CIA).
