JATO, or Jet-Assisted Take Off, is a technology used primarily in aviation to enhance the takeoff performance of aircraft. It involves the use of additional thrust provided by rocket engines or other propulsion systems, allowing planes to take off from shorter runways or carry heavier loads. This method is particularly useful in military operations and for certain commercial aircraft. The concept of JATO dates back to World War II, where it was first implemented to assist fighter planes. Today, it is still utilized in various military aircraft and some specialized civilian planes, demonstrating its importance in aviation history and technology.
