Most of the cars or other machinery and equipment burn gasoline or diesel, while the airplane flying in the air burns not gasoline or diesel, but kerosene. Why?
There is only one reason why airplanes burn kerosene instead of gasoline and diesel. Many people think that it is very cold at high altitudes. It is cold to minus 50 or 60 degrees. The display of the airliner shows this, and you can feel it when you stand on Mount Everest. Here comes the question: Why are falling meteors or satellites burnt to ashes? That’s right, when flying at supersonic speeds, air friction heat is greater than air cooling.
