Video: Why can't a plane fly into space?

The gravity of the Earth and the dilution of the atmosphere are barriers that prevent aircraft from flying into space like spacecraft.

The speed of the aircraft does not escape Earth's gravity.

You can't even fly halfway, partly because of Earth's gravity . You need to escape it to fly to the universe. This requires a minimum speed of 40,233 km / h. The record of the world's fastest aircraft is now 8272km / h.

Another problem is the atmosphere . As you fly higher, the atmosphere gets thinner, which creates two serious problems.

1. Problem 1: Fewer gas molecules mean more difficult aircraft in the air.
2. Problem 2: Less oxygen makes fuel more energetic for the engine to burn.
