Factual error: In the scene at the Miami hydroplane race, Mike McCormick spies a long haired boat pilot and naively asks one of the locals, "Is that Grizzly Adams?", to which he is answered facetiously, "Yeah, that's Dan Haggerty." The story takes place circa 1971, but actor Dan Haggerty didn't play Grizzly Adams 'til 1974.
Factual error: In the scene at the Chicago Yacht Club both the Sears Tower & the Standard Oil Building are plainly visible in the distant skyline. These two towers weren't both done 'til 1974., but the story takes place in the year 1971.
