Less famously, but with far greater implications, was the innovative use of pre-prepared 'pace-notes' which allowed Klenk to identify and communicate upcoming road bends in rapid shorthand to Kling. This system proved so effective that it is used in all motor sports involving a navigator today, such as stage rallying. The highly organized Lincoln teams also used a similar system. Only one person was killed in this event, Santos Letona of Puebla, Mexico, who died in a crash near the town of Texmelucan on the third stage between there and Mexico City.
