I have been reading Horrible Science. here are some facts about Flight.

• The reason you can 'break the sound barrier' is because when the plane goes too fast for the air to get out of the way, making a 'wall'. When you break the sound barrier you are breaking this wall of air.
• The way jet engines work is that they suck in air, and spit it out the other end.
• As children the Wright Brothers' father had bought them a helicopter toy that was powered by a rubber band When it broke their father bought a second one, which their teacher confiscated. Think about it, teachers held back the creation of the plane!
