World War II: Secrets from Above

The concept is great, and for the most part the series is pretty decent. However it just seems that research was lacking in the most simple parts. For instance: in the series 2 episode Breakout from Normandy the Tiger II (King Tiger) is, for the entire episode, substituted for the Tiger I, to the point where they go through Michael Wittmann's assault displaying the graphic of him commanding a Tiger II, not a Tiger I. Any very amateur WW2 historian knows the very large difference between these tanks, their deployments, and their costs. So this really tends to ruin what should have been a pretty good series, as they go on location, match up the battle locations, and otherwise show some decent stuff. But the Normandy episodes problems aren't the only errors in the series, there are other smaller ones that should have been picked up on other episodes, but it's the most glaring and disappointing.
