General Fugh wasn’t the first Chinese flag officer in the US military. That was Brigadier Uzal G Ent, who led the raid on the Ploesti oilfields in 1943 and personally selected Paul Tibbets as pilot of the Hiroshima mission. Brigadier Ent’s grandfather was one of two ethnic Chinese Thais who settled in South Carolina in the 1840’s. They were Chang and Eng Bunker, the original Siamese twins. I’ve not been able to find out which one was his granddad.
Anotherof the Bunker\’s descendants also joined the Air Force.
