Why can’t I fly into space in an aeroplane?

All objects, even aeroplanes, are glued to the surface of the Earth by gravity. If you wanted to escape this unseen force, you would have to travel at a speed of at least 40,000 kilometres per hour (25,000 miles per hour). Only space shuttles are designed to achieve this speed. A mixture of liquid hydrogen fuel and liquid oxygen is burned under high pressure to help the shuttle’s rockets reach this speed and push it out of the Earth’s atmosphere into orbit.
