NASA's Ultra-Efficient Engine Technology Program hosts this educational site intended mainly for grade school students. Visitors can browse several sections related to aeronautics and flight technology, including one that discusses career paths leading to work in these fields. An introduction to aerodynamics explains how an airplane's systems and design contribute to its flight. The operation of a jet engine is described in a video clip of a NASA researcher, and details of several different types of jet engines are given in the accompanying text. A new feature on the Web site is a trivia game that teaches children about the history of the Wright brothers and their work.
