Leland Snow, the godfather of the modern ag aircraft, begins designing his first ag airplane, the S-1. The 23-year-old Snow completed test flights with the S-1 in 1953. Snow flew the S-1 on dusting and spraying jobs in the Texas Rio Grande Valley and in Nicaragua until 1957. He followed up the S-1 with the models S-2A and S-2B, which were built when Snow moved production facilities to Olney, Texas, in 1958.
