He was delayed for 10 days by monsoon rains, during which time the wife of Prajadhipok, the King of Siam, presented him with a rare Siamese cat. Koenig-Warthausen named it "Tanim", and the cat accompanied him for the rest of the journey. In Bangkok, he encountered and his wife Violette Selfridge, similarly then on their way to being the first couple to complete a partial aerial circumnavigation, in a de Havilland DH.60 Moth, ahead of Koenig-Warthausen. He also engaged in efforts to locate the then missing Joseph Le Brix who had gone down on the coast of Burma near Moulmein in an attempt to break a speed record. Koenig-Warthausen finally left Bangkok on 25 March, heading south to Prachuap Khiri Khan and Songkhla, and experiencing another tropical storm while flying over Penang before arriving at Singapore. He stayed there for three weeks, making the short flight south to cross the Equator. Having booked, and then cancelled, passage home for himself and his aircraft several times, it was only then that he decided to continue the flight around the world. Having been advised not to fly over Indochina, he travelled by ship to Shanghai, China, and then flew to Nanking. From there Koenig-Warthausen sailed east to Kobe, Japan, where he spent ten days, and, after another three weeks in Tokyo, he sailed for the United States from Yokohama on the "Siberia Maru", arriving in San Francisco via Honolulu on 8 June. His aircraft was reassembled and repaired at Alameda, where, on learning of his fellow German flyer's death, it was renamed "Hünefeld" on his honour. After ten days he set off for Los Angeles. En route, a large bush fire prompted him to envision aerial firefighting using flame retardant chemicals as part of the future for aviation. In Los Angeles, he met fellow Swabian, film producer Carl Laemmle, before flying to San Diego, then Tucson, Arizona, and El Paso, Texas. At El Paso, early on the morning of 12 July, a car crashed into the taxicab taking him to the airport. He was thrown from the car, suffering a concussion, and seriously injuring his leg. He spent the next two months recuperating, and was also informed that if he could reach New York before 31 October he would win the Hindenburg Cup for 1930.
