In 1958, my mother bought an encylopedia set for me as I was a kid in school and liked to read. The set was named
The Book of Knowledge... don't know if the books are still being made.
Being a kid, whose Dad and uncles were all in the War, I was interested in the WWII parts of the books. A couple of the photographs of this plane being struck in the stabilizer were included, along with either a caption or a short story. There's no mistake about the photos or the story, and I must have looked at both hundreds of times over the years. Find the books at some flea market/garage sale, and you'll have the photos and the short caption/story about this plane.
Anyway, the books were printed only 14 years after the War, and told the story that the B-17 DID make it back to base. Now, that doesn't make it true, but it does show that if the survived-the-hit story is correct, then its origins may go back much further than we might think.
The photos of this incident have been well known over the years, and the story was always that the plane and crew survived. It's been in the last few years that the story has changed to one of a loss. Was the story bad history then, or poor memories now?
For what it's worth from an old man.
