PM. Of the fifteen teams that participated in the draw, just four were on the course: Golden Eagle, Aloha, Woolaroc, and Miss Doran. A series of ships were strung out along the route from San Francisco to Honolulu to transmit radio signals (allowing radio-equipped airplanes to take bearings), mark distances, and provide emergency aid if needed. In addition, the Navy's sole aircraft carrier, , was put on standby in San Diego. Woolaroc and Aloha finish Woolaroc flew a great-circle route, flying at an altitude of , above the cloud cover. The navigator, Davis, used sextants and smoke bombs to calculate course and wind drift; although the radio beams from the picket ships stationed along the route helped guide the aircraft, Davis used it only to check the course plotted via traditional instruments. Of the four aircraft headed to Hawaii, only Woolaroc had a two-way radio capable of sending and receiving messages. In fact, Davis had packed a spare radio and repair parts based on Bronte's prior experience in July. The crew radioed Wahiawa Radio Station, next to Wheeler Field, when they were approximately out with an estimated remaining time of 2 hours. They were greeted in Hawaii by a crowd estimated between 25,000 and 30,000, and escorted by a Boeing PW-9 out of Wheeler Field. Goebel and Davis won the race in 26 hours, 17 minutes, earning them the US$25,000 first prize. After their sponsors were paid, Goebel and Davis split the remainder, earning them each US$7,500. Marguerite Jensen, the wife of Martin, anxiously asked the crew of Woolaroc if they had sighted Aloha, which had departed just ahead of Woolaroc; they replied they had not, adding to her anxiety. Jensen flew much of the way at a low altitude of above sea level, helping fuel economy but making it impossible to sight the stars for navigation. Three times during the flight, Jensen attempted to climb to , but went into a tailspin each time; once Jensen inadvertently commanded a shallow dive and skimmed the water with the landing gear, prompting him to rise to a safer altitude of . The next morning, at 9:30 AM (Hawaii time) on August 17, Jensen calculated they should be close to Hawaii, based on average speed and time elapsed. Over the next two and a half hours Schluter, the navigator, attempted to determine their position from the sun. At noon on August 17,
