F-5s were bought by aerial survey companies and employed for mapping. From the 1950s on, the use of the Lightning steadily declined, and only a little more than two dozen still exist, with few still flying. One example is a P-38L owned by the Lone Star Flight Museum in Galveston, Texas, painted in the colors of Charles H. MacDonald's "Putt Putt Maru". Two other examples are F-5Gs which were owned and operated by Kargl Aerial Surveys in 1946, and are now located in Chino, California at Yanks Air Museum, and in McMinnville, Oregon at Evergreen Aviation Museum. The earliest-built surviving P-38, "Glacier Girl", was recovered from the Greenland ice cap in 1992, fifty years after she crashed there on a ferry flight to the UK, and after a complete restoration, flew once again ten years after her recovery.
