Leland Snow was an American aeronautical engineer known for designing and developing agricultural aircraft.
By 1953 the aircraft was completed and test flown, and Snow began dusting and spraying both in Texas and elsewhere.
Snow sold the company to Rockwell-Standard in 1965, and as part of the deal became vice president of its Aero Commander division, manufacturers of a whole range of general aviation aircraft.
In 1977 the design was sold on the Ayres Corporation who produced it as the Ayres S-2R Thrush, and in 2003 after yet another transfer and further modifications, an aircraft based on the original Snow design saw it manufactured and sold as the Thrush Corporation 510[a] where it was still in production in 2024, over 60 years after its first flight.
Snow continued to expand the company and the range of aircraft produced, right up until his death on February 20, 2011, in Wichita Falls, Texas.
