Abstract

You can make a very simple hovercraft with a stiff, disposable plate—a pie plate should work well—and a balloon. Glue a square of cardboard in the center of the bottom of the plate. Make a small hole through the center of both of these layers. Enlarge the hole slightly with a pencil. Push a balloon through the hole so that the opening is on the front side of the plate, and rest of the balloon sticks out from the back. Blow up the balloon, then set the plate down (balloon side up). What happens? Add weight (using clay or pennies) symmetrically around the edge of the plate to measure amount of lift force. Can you control the direction of motion by making an outlet in the edge of the plate? (Parker, 2005, 14–15) Can you see any effect of changing the hole diameter? (This may be hard to measure.) You can also research and build more elaborate types of hovercraft using battery-powered fans for lift.

Aerospace Engineer
Humans have always longed to fly and to make other things fly, both through the air and into outer space—aerospace engineers are the people that make those dreams come true. They design, build, and test vehicles like airplanes, helicopters, balloons, rockets, missiles, satellites, and spacecraft. Aerospace Engineering and Operations Technician
Aerospace engineering and operations technicians are essential to the development of new aircraft and space vehicles. They build, test, and maintain parts for air and spacecraft, and assemble, test, and maintain the vehicles as well. They are key members of a flight readiness team, preparing space vehicles for launch in clean rooms, and on the launch pad. They also help troubleshoot launch or flight failures by testing suspect parts.

Pilot
Pilots fly airplanes, helicopters, and other aircraft to accomplish a variety of tasks. While the primary job of most pilots is to fly people and cargo from place to place, 20 percent of all pilots have more specialized jobs, like dropping fire retardant, seeds, or pesticides from the air, or helping law enforcement rescue and transport accident victims, and capture criminals. Pilots enjoy working and helping people in the “third dimension." Aviation Inspector
Aviation inspectors are critical to ensuring that aircraft are safe to fly. They conduct pre-flight inspections to make sure an aircraft is safe. They also inspect the work of aircraft mechanics, and keep detailed records of work done to maintain or repair an aircraft. As problems are identified, they may make changes to maintenance schedules, and may be called upon to investigate air accidents.

Marine Architect
Water covers more than 70 percent of Earth's surface, and marine architects design vessels that allow humans and their cargo to cross through or under those waters safely and efficiently. Some of their watercraft designs are enormous, like merchant ships, which carry huge loads of oil, cars, food, clothing, toys, and other goods, across thousands of miles of open waters. These ships are essential for trade between countries. Other vessels are smaller and more specialized, like luxury yachts or cruise liners. Still others are designed for military purposes.
