"The development of the Kristi snow vehicles began in early 1947 in the form of a very unusual snow plane. This propeller driven vehicle utilized a control by which the operator could tilt the machine from side to side, in effect raising one ski and lowering the other to negotiate up to 45-degree side slopes and permit high-speed turns without skidding.
