Snow began designing his first aerial application aircraft, the S-1, in 1951 when he was 21 years old.
In August, 1953, the S1 flew for the first time, powered by a 190 hp Lycoming. Unusually for a US ag-plane, the pilot sat between the engine and the hopper, and, unlike later Snow models, the aircraft had wing struts.
The aircraft was successful, enough for Snow to take it to Nicaragua for a season the following year.
To give it more power, it was fitted with a Continental radial of 220 hp. The radial engined S-1 lost its wing struts.
Dam¬aged by a thunderstorm in 1958, this aircraft was destroyed in a warehouse fire a few years later.
That airplane remained in production until 1957, after which Snow introduced the S-2A and S-2B models.
