At 3:00 p.m., the races began with a competition between Army and Navy trainer aircraft from Sand Point to Renton through Kirkland and back to Sand Point. Then observation planes flew a relay race from Sand Point to an airfield south of Tacoma, where the planes landed to pick up a letter from the Postmaster addressed to the Mayor of Seattle.
The only mishap of the day was when Army Lt. L. C. "Goldie" Goldsmith damaged his wheels landing in Pierce County. Goldsmith was obliged to take the train back to Sand Point.
Civilian pilots raced their aircraft and some Army bombers showed off formation flying. The latest Boeing pursuit airplane appeared and flew at speeds said to approach 200 mph.
