Science fiction author Isaac Asimov was the show's scientific adviser.
The faux science on the show wasn't necessarily because of any hesitancy on the part of the production staff to be scientifically accurate (Isaac Asimov was a scientific advisor, at least on the pilot), but more because of the production realities of weekly television. They simply couldn't afford to launch and land a rocket ship every week, unless they fudged the science more than a bit.
Estes Rockets made a prototype of a model rocket version of the Vulture. It was never brought to market.
This winter offering from ABC went head to head against popular shows WKRP in Cincinnati and Little House on the Prairie. That likely explains why it managed a mere 20 episodes.
Andy Griffith told People magazine he initially turned down the show because he thought it was Saturday morning television.
