Fighter aircraft were first deployed in combat during World War I, less than a decade after the airplane’s development. In 1939, the first jet plane was created. It quickly became a standard feature on both military and commercial planes. What is the working principle of a jet engine? With the help of a swiftly spinning fan, the engine first suckers air into the air. The compressor’s blades then compress the air, increasing the pressure. After that, the air is combined with the fuel and ignited by a spark. The burning gases erupt from the engine’s rear, propelling the plane forward. Jets have made frequent appearances in popular culture, such as in songs and films. The 1986 action picture Top Gun, the television series JAG, many anime cartoons, and countless more romanticized the concept of fighter jet flight. Jet aircraft toys and buildable models are also widely available. The flight performances by well-known aerobatic performers, such as the Blue Angels, draw large crowds.
