I added the BoB to the top of my netflix list as soon as I saw that clip and watched the movie over the weekend. My conclusion? Don't sweat the clip. It's put together from many different scenes throughout the film, some more than an hour apart. On the other hand, there is a scene in the movie where He 111s from Norway attack northern England without escort because there's an assumption that Hurricanes and Spitfires won't have the range to intercept them from their southern bases. Needless to say, it doesn't go well.
The movie does a nice job of recreating the strategic moves and blunders of the battle. Specific emphasis is placed on two things: tactical warfare against forward fields vs bombing London, and free fighter sweeps vs close escort duty for the 109E. As much as historians will debate what really happened, the movie goes along with the "woops" theory, that it was a lost He 111 crew bombing London on mistake that began a chain of events that lead, eventually, to the Blitz. The English bomb Berlin in retaliation, Hitler gets mad, and orders that London be bombed instead of forward airfields, etc. You know the story. The decision exacerbates the range issue of the 109E because London is further away than the RAF forward airfields, the RAF regroups, and successes mount against the Luftwaffe fighter escort which is tied down low to the He 111s.
The aircraft I saw were (or were supposed to look like):
Spitfire Mk I
Hurricane Mk I
Bf 109E-3
He 111
Ju 87
No Bf 110, Do 17, or Ju 88.
