An aircraft hangar is a large building designed to house and protect airplanes and other types of aircraft. These structures provide shelter from weather conditions, such as rain, snow, and extreme temperatures, which can damage the aircraft. Hangars are typically found at airports and airfields, and they come in various sizes to accommodate different types of aircraft, from small private planes to large commercial jets. In addition to storage, aircraft hangars often include maintenance facilities where technicians can perform repairs and inspections. They may also have office spaces for flight operations and pilot training. Overall, hangars play a crucial role in ensuring the safety and longevity of aircraft.
