Why is an aeroplane unable to fly in a vacuum?
Answers
A main reason airplanes can't fly in space is because there is no air. According to NASA, large commercial airplanes typically can't fly higher than 7.5 miles. At this altitude, the air isn't dense enough to support a large airplane. ... As the jet fuel and air burn, it produces thrust to propel the jet through the air.

Another reason airplanes can’t fly in space is because they require air to generate combustion. Jets, for example, burn a combination of jet fuel and air in their engines’ combustion chamber. As the jet fuel and air burn, it produces thrust to propel the jet through the air. This same principle applies to automobiles with a combustion gas engine. Cars, trucks and SUVs all use air as part of their combustion process. If an airplane flies in space, it won’t be able to suck in fresh air with which to supply its engines, resulting in loss of propulsion.
The bottom line is that airplanes can’t fly in space because there is no air in space. Airplanes rely on air to produce both lift and propulsion. Since there isn’t any air in space, airplanes must stay within the Earth’s atmosphere.
