Having seen "Those magnificent men in their flying machines" as a 21-years old for the first time in January 1967, certainly betrays my age too! I lived in Australia then and was on my way by train from Brisbane to Melbourne. In Sydney I had to change trains, with many many hours to spare between them. Walking through the city I noted a cinema where "something about flying" was being shown, so I made the tough choice not to continue sampling the various Sydney beers in lots of pubs, but went to see the film. I never regretted the decision, and made up for the alcoholic loss later.
Around the same time "The Blue Max" was showing, which I saw too. A couple of totally different, but equally entertaining films!
