Moon Fun Chin (Chén Wénkuān, 陈文宽) was born in 1913, Zhongshan, Guangdong province in China. His father who was an American citizen of Chinese descent, took the young Moon to Seattle, Washington in USA. Moon’s family moved to Baltimore where he later completed his high school education. At a young age, Moon had already exhibited a keen interest in aviation. Soon after completing his high school education, he decided to enroll in Curtiss Wright Flying School and graduated with a Commercial Pilot Licence.
As good luck would have it, Curtiss Wright had a joint venture with the then China’s Nationalist government to operate a major airline in China. Moon’s uncle had a friend whose name was William Langhorne Bond. In 1931, Bond was the Operations Manager for the China National Aviation Corporation (CNAC), a joint venture airline operated by Curtiss Wright and the Chinese Nationalist government. However, Pan-Am took over from Curtiss Wright In 1933.
Upon hearing that CNAC intended to expand its operations in 1933, Moon’s uncle coaxed his young, energetic nephew to come to China to meet with Bond.
Bond decided to hire Moon for CNAC. However, Moon commenced work in CNAC not as an aviation pilot, but as an aviation mechanic due to his prior work experience before joining CNAC. Two weeks later, Moon was finally given the opportunity to be a co-pilot of an aircraft on a Shanghai-Beijing route. While on the ground, he still multi-tasked as a mechanic. In 1936, Moon was promoted to “captain”. As a captain, he flew on a “Stinson” which was based in Chengdu. Everyday, he flew on the Chengdu – Chongqing route. En route to Chongqing, he picked up tourists who visited the Yangtze River and other passengers who wished to continue on their journey to Chengdu. He flew transport missions that included flights over the Himalayas. From time to time, Moon would fly to Rangoon (Burma) and Hanoi (Vietnam) when needed.
Moon was only 20 years old when he began his flying career as a co-pilot in the Loening. The Loening Seaplane was one of the first of the "shoehorn-float" civilian aircraft that could land and float on sea water.
By the time Moon became a captain, he flew on several other types of aircrafts, such as the Stinson, Douglas Dolphin, Sikorsky S-38, DC-2 and also the DC-3.
