Actually, the last combat mission was flown by a photo unit of B-32 Dominators on August 18.
They were intercepted by 4 N1K George fighters, Photographer Staff Sergeant Joseph Lacharite was wounded in the legs (his recovery required several years). Sergeant Anthony Marchione, a photographer's assistant, helped Lacharite and then was fatally wounded himself.
Marchione was the last American to die in air combat in World War II.
My second cousin, who is still alive, flew B-32s in the closing weeks of the war. He transitioned out of B-24s. Many people, including some who work in aviation museums, have never even heard of the B-32.
The really weird but true story is how the Brits, French and Japanese all fought together in Vietnam against the Viet Minh from Sept 45 through Spring of 1946!
Heck of a tail on that plane.
