This was a very timely cover because the SK-3 "Jupiter," designed by Clayton Folkerts of Omaha, had just won the Thompson Trophy Race. The plane exemplified American trial-and-error design. It had a wooden propeller of very high pitch and one of the shortest wingspans in racing.

The Thompson trophy race was one of the National Air Races of the heyday of early airplane racing in the 1930's. Established in 1929, the last race was held in 1961. The race was 10 miles long with 50-foot-high pylons marking the turns, and emphasized low altitude flying and maneuverability at high speeds. As the race was flown around a closed course, crowds in the grandstands could easily see much of the spectacle.
