“In a way, the P-61 was unofficially credited with the last Allied air kill of World War 2. Unofficial in that the enemy aircraft - a Japanese Nakajima Ki-44 - was reportedly in evasive maneuvers after having encountered an American P-61, its guns blazing on the Nakajima fighter.
The enemy fighter flew defensively just feet above the waves and eventually crashed itself along the surface of the ocean, ending the life of the pilot and his mount in a fiery explosion. The P-61 in question was a P-61B-2 aptly-named “Lady in the Dark” and under the control of Lieutenant Robert W. Clyde. The event occurred sometime between August 14th and 15th. If credited, the kill would have been accomplished without a single shot being fired..” (via)
