Why U-2 can fly so high?
Why U-2 can fly so high? High aspect ratio wings give the U-2 glider-like characteristics, with an engine out glide ratio of about 23:1, comparable to gliders of the time. To maintain their operational ceiling of 70,000 feet (21,000 m), the early U-2A and U-2C models had to fly very near their never-exceed speed (VNE).
Is there oxygen at 35000 feet?
Planes have lower oxygen levels If this didn't happen, everyone inside the plane would die, as the low air pressure at the elevations planes fly (typically 35,000 feet or so) means there isn't enough oxygen present for your body to function.
Why do planes fly at 41000 feet?
The biggest reason for flying at higher altitudes lies in fuel efficiency. The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed. Less wind resistance, more power, less effort, so to speak.
Why is U-2 called Dragon Lady?
The U-2, nicknamed Dragon Lady after a comic strip character of the 1930s, has been used by the U.S. Air Force, the Central Intelligence Agency and the National Aeronautics and Space Administration.
What can fly at 80000 feet?
Can you fly at 80000 feet? The US Air Force U-2 reconnaissance aircraft flies at 72 000 feet almost every day for many hours. The world's fastest manned aircraft, the SR-71, flew for many years at 80 000 feet and higher.
Can a plane fly at 60000 feet?
There are no specific regulations governing civil aircraft operations beyond the altitude of 60,000 feet. Nevertheless, certain exceptional aircraft like the Concorde and the Tupolev Tu-144 have managed to ascend to altitudes of FL600 (equivalent to 60,000 feet).
