Vertical Takeoff and Landing, or VTOL, refers to aircraft that can take off, hover, and land vertically. This capability allows them to operate in confined spaces where traditional runways are not available. VTOL technology is commonly used in helicopters and some advanced drones, enabling them to perform various tasks, including search and rescue, military operations, and urban air mobility. VTOL aircraft typically use rotors or fans to generate lift. Some designs, like the Harrier Jump Jet, can transition between vertical and horizontal flight, making them versatile for different missions. The development of VTOL technology continues to evolve, with new innovations aimed at improving efficiency and safety.
