It is strange that the wonderful BBC series "Wings Over the World" is not listed in the IMDB, nor is Richard Todd given credit for narrating it. This Sikorsky episode was the second in the series.
All of the episodes are a must for aviation buffs. The archival footage is tremendous, and Todd's narration is intelligent and clear. What I like best, however, is Toby Gilk's haunting music. Not only is it beautiful, it fits its accompanying scene perfectly.
This particular episode shows how brilliant Sikorsky was in general aviation, not just helicopters. The interview with his son is very illuminating and highlights the brilliance of the man.
