There was only one time that an AC-130 might have been confused with Puff (also called Spooky) that was during its secret combat eval circa 1967.
I volunteered for AC-130 duty during Vietnam and couldnt get into the program until 1975. Proudly flew the unfriendly skies with Specter until 1990 and still work with that platform today doing test and development.
