Supposed error in episode Saturn V

In the episode, part 5, they speak of Apollo 8 as being the 'first time human lives were at stake', in the testing of Apollo. Which would seem a 'grave' error, in that 3 lives were ALREADY lost in the Apollo 1 fire(Virgil I. "Gus" Grissom, Edward H. White II and Roger Chaffee) and the successful, but forgotten Apollo 7 orbital test was manned (Eisele, Schirra and Cunningham) as well.

But both of those flights were using the Saturn 1B booster. This episode was about the Saturn V booster, which actually was a totally different design and team. So in the focus of the episode, they were right and DO say it was the first time the Saturn _V_ testing was exposing human life to danger.

I do traveling classes with kids on hands on science. Things like dinosaurs and particularly on the Apollo Space program, so I notice oddities like this. ;-)
