Jet Aircrafts

Definition

Jet aircrafts are powered by jet engines, which use the principle of jet propulsion to generate thrust. These aircraft revolutionized air travel and military aviation after World War II, enabling faster, higher, and more efficient flights compared to earlier propeller-driven planes. The development of jet aircrafts marked a significant advancement in aerospace technology and had far-reaching impacts on global transportation and warfare.
