Excellent movie that tries to capture the magic of flight during that period of history. The characters are all simply fun to get to know. They take a bit of license with the flying details, but the methods used to create the flying scenes were novel at the time. To me, much better than today's digital fakery. There was much thought involved in the re-creation of the "flying machines' shown. While the engines had to be "souped up" for safe performance, the actual airframes and model types were as true to original as possible.
The film is really dated, but its still pretty fun.
