A hangar is a large building used for storing and maintaining aircraft, such as airplanes and helicopters. These structures provide protection from weather elements like rain, snow, and sunlight, which can damage the aircraft. Hangars are typically found at airports and airfields, where they serve as essential facilities for aviation operations. Inside a hangar, mechanics and technicians perform routine maintenance and repairs on the aircraft. The space is equipped with tools and equipment necessary for servicing engines, wings, and other components. Hangars can vary in size, accommodating everything from small private planes to large commercial jets, ensuring safe and efficient operations in the aviation industry.
