During the Boeing 737 Renton Factory tour at Aviation Geek Fest this year, I thought I heard the tour guide say something about elephants walking the factory floor. Wait… what? I wasn’t sure if I heard it right, or if maybe he was having some fun with the guests. I mean, I have been in the factory many times, done a few stories, but elephants had never come up. I also know that the Boeing tour guides are super knowledgeable and he mostly likely wasn’t lying. So I decided to reach out to Boeing Historian Michael Lombardi and, sure enough, the circus did come to town! Kind of — way back in the 1940s.
