The U2 was one of _______ military planes of the Cold War. It was designed to fly high over a foreign country, take pictures and gather information.
The U2 was built in Area 51, a secret place in Nevada, known for UFO sightings. The US Air Force built the area to create such a secret plane and test new weapons.
The single-pilot plane could fly at an altitude of over 20 km above the earth’s surface. With its special cameras it could take detailed photos and close-ups of objects on the ground. Today, the US Air Force still operates a modified version of the U2, however it is not used as a spy plane any more. Current planes have a larger fuselage and need less fuel than their predecessors of the Cold War. They are also equipped with more sophisticated instruments. Some of them fly over Afghanistan and support American soldiers on the ground. They also saw action during the Gulf War and the conflict in the Balkans.
U2s are also used for research. NASA uses the former spy planes for tests in the atmosphere.
