    Have you watched movies that take place in the future? You may have seen people travelling in lying cars or using spacecraft to explore other planets. These movies could be showing us what air and space travel will be like in the future.

    Imagine the year is 2040. Your new jetpack will take you to the store. A jetpack is something that a person straps on like a backpack. Fuel and air are burned in an engine. Then hot air is forced out of the exhaust, or the bottom of the jetpack. This thrusts (用力推)the person wearing the jetpack up into the air. A person wearing a jetpack can fly.

    There are jetpacks that have already been made. One jetpack can stay up in the air for minutes. It has a range of 30 miles.

    Most experts think that jetpacks would not be good for everyday travel. A group of scientists has started a project called myCopter. The group is studying very small aircraft and wants to know if the use of tiny aircraft could be possible in the future.

    The group is thinking about how the tiny aircraft could work. The owners of the aircraft won't be trained pilots. Experts want to build aircraft that fly together. Each aircraft could send out signals to other aircraft nearby. This will help keep the aircraft from getting too close to each other. The owner of the aircraft will choose the main direction. But the aircraft will mostly be controlled by a computer on the aircraft.
