Wingsuit flying is a fun sport where you jump from the sky with a special suit. This suit has extra fabric between the arms and body to help you glide in the air, like a bird. People usually jump from an airplane or a high place like a cliff or mountain. After flying in the air, you must use a parachute to land safely. The suit has zippers so you can control your parachute. People sometimes call these suits "birdman suits," "squirrel suits," or "bat suits" because they look like the wings of these animals. Long ago, a man named Franz Reichelt tried to fly with a suit from the Eiffel Tower, but he fell and did not survive. Later, in 1930, a young American man named Rex G Finney made another suit and flew with it in the United States.

Drones are flying machines with no people on board. They were made a long time ago for the army to do jobs that were too boring, dirty, or unsafe for people. Nowadays, drones are very important for the armies around the world. Drones can do many things without being used by the military. They can take pictures from the air, check on large areas, help farmers, watch for forest fires, keep an eye on rivers and the environment, help the police, look at buildings and roads, stop illegal things, deliver products, and even be used for fun and racing. The word "drone" has been used for many years. It first described remote-control flying machines used to practice shooting. These older drones had names like Queen Bee and Queen Wasp. Today, drones use smart technology to fly on their own, such as cloud computing, computer vision, and artificial intelligence. Some drones are even smart enough to learn as they do tasks. Drones that people use for fun may have cameras and can fly by themselves. A drone is a machine that can fly without a person inside, can lift itself up, can fly on its own or be controlled from far away, and can do different tasks. Drones can be simple or very advanced and can have different tools for different jobs. The word "drone" is usually used for military drones, but not for flying machines that are just missiles.

A jet pack is something you wear on your back that helps you fly in the sky. It has jets that push you through the air. People have thought about jet packs in stories for a long time. The first real jet packs were made in the 1960s. Jet packs work in different ways, but it is hard to use them for a long time. This is because of the air around us, the pull of the Earth, the kind of fuel they use, and because our bodies are not made to fly. Usually, jet packs are used for fun and to show off in shows. Astronauts in space sometimes use jet packs. In space, it's easier because there is no air to slow them down and they do not feel heavy. A special type of jet pack that also has jets for the arms is called a jet suit. This helps the person move better in the air. A jet pack makes you fly by pushing against the air. It has to push hard to lift the person and the jet pack. It must push stuff down to go up. Some jet packs get power from a place on the ground, but many need to carry their own fuel. This makes them heavy and they can only fly for a little bit, not for a long time like in stories. The first idea for a jet pack was made in 1919 by a man named Alexander from Russia. People thought it was a good idea. He also thought about adding wings to it.
