Amazon is out to rewrite gender history. There were no women involved in the historical event portrayed. James Glaisher was a real aeronaut and his reaching 26,000 feat was a real achievement. However, his assistant, Henry Coxwell, was a man, not a woman. The person was Glaisher, who freed the valve. No woman was present on the flight, and Coxwell was not transgender either. If you like fake history and can suspend belief, you may enjoy this Amazon propaganda film. If you are not into fantasy role switching, you may want to avoid it.
