Airstrips are flat, open areas designed for the takeoff and landing of aircraft. They can be found in various locations, including rural areas, military bases, and emergency sites. Unlike traditional airports, airstrips are often smaller and may not have extensive facilities or services. These surfaces can be made of grass, dirt, or paved materials, depending on their intended use. Airstrips are crucial for activities such as crop dusting, search and rescue operations, and military operations, providing essential access to remote regions where larger airports are not available.
