The Conquest of the Air

Firstly, many reviewers have already mentioned this film as listed 1936, but as I write it has transported itself back to 1931. Churchill as PM suggests it's final version is almost 10 years younger.

The drama elements of this docu-drama are in the first half and are both educational and fun in an almost Pythonesque way (you'll know what I mean when you get to the 3rd tower jumper). As the amount of archive material becomes more available, obviously, in the 20th C. We get more documentary and in last segment slide into necessary propaganda.

Worth a watch, I learned something, not all that much, but something.
