This is one of the competitors in the Dole Race or Dole Derby which was an air race from Oakland to Hawaii from August 16-18, 1927. There were fifteen original entries but due to various accidents and mechanical problems only eight planes actually took off and only two ever reached Hawaii. The race was sponsored by James Dole of Dole Hawaiian Pineapple. First prize was $25,000 and second $10,000. This negative shows the monoplane "Oklahoma" on the runway. An automobile is parked in front of the plane with a woman posing by its front fender. A small group of people are standing around the plane behind a rope. The Oklahoma was flown by Bennett Griffin with Al Henly as navigator. The plane was sponsored by Phillips Petroleum. The Oklahoma was the first plane to take off in the race at 12 o'clock on August 16, 1927. The Oklahoma returned to the Oakland airport a little after 1:00 apparently because of engine trouble. The plane never returned to the race due to a bad engine. The pilot, Griffin, later became manager of Washington National Airport and Henly, the navigator, was killed in a plane crash in Texas in 1929.
