On August 10, Hollywood pilot and actor Frank Clarke either withdrew or was disqualified from participating in the race with his navigator, Jeff Warren, in "Miss Hollydale", an International F-17 biplane. Clarke announced he would attempt the world endurance record instead and took off abruptly on August 13 with his sponsor, Charley H. Babb, leaving the other contestants fuming. One day later, Clarke sent a telegram to the race sponsors from Los Angeles, apologizing for the furor and officially withdrawing from the race.
