Barstow Daggett Airport — Daggett, United States

Few outside the Mojave Desert recognize DAG as the code for Barstow Daggett Airport, situated near Daggett, California, a location whose bone-dry climate has long made it valuable for aircraft storage and testing. Over the decades, the airfield has been used by aerospace and airline companies to store retired or surplus aircraft in the open desert air, where low humidity slows corrosion far better than more humid regions. DAG also sits along the historic path of early transcontinental air routes and Route 66, giving it a place in the broader story of American aviation infrastructure development. Today the airport functions mainly as a general aviation and testing facility rather than a passenger hub, reflecting its remote high-desert setting east of Barstow.
