Flying-M Ranch, Historic ranch and airfield in Lyon County, Nevada.

Flying-M Ranch is a 7,139-acre ranch and airfield in Lyon County, Nevada, between the Wassuk Range and the Sweetwater Mountains, west of Hawthorne. Its runway measures 5,500 by 50 feet, and a hangar holds about a dozen historic aircraft that remain airworthy. The surrounding desert produces thermal soaring conditions, and a single white glider with long, thin wings can be seen above the rectangular green fields, with brown barren slopes behind.

The ranch was named Flying-M by its earlier owner Stanfield Murphy, and Barron Hilton kept the name because his wife was Marilyn. Hilton used the land as the base for the biennial Barron Hilton Cup gliding competitions. In 2016 the National Fish and Wildlife Foundation bought the ranch for $19.4 million to secure water rights for Walker Lake, with a life estate for Hilton.

The name comes from Stanfield Murphy, who called the ranch Flying-M; Barron Hilton kept it because his wife was named Marilyn. Winners of the biennial Barron Hilton Cup were invited to stay a week at the ranch. A hangar holds about a dozen historic aircraft, still airworthy.

The ranch lies west of Hawthorne, about 75 mi (121 km) south of Reno, between the Wassuk Range and the Sweetwater Mountains. Its airfield has a 5,500 by 50 ft (1,676 by 15 m) runway and a hangar holding about a dozen airworthy historic aircraft. It is private land, so access and any flight activity need prior arrangement with the owner.

The property was purchased in 2016 by the National Fish and Wildlife Foundation to secure water rights for Walker Lake restoration. This shift shows how the historic flight facility now serves water conservation for the local ecosystem.
