Great American classic that you can get for free on kindle. I was supposed to read this back in high school but wasn't not interested at the time. But now with the benefit of age I can really appreciate it.

While this film may not win an academy award the aerial fighting sequences make it well worth the money ---plus the acting from relatively unknown actors was not bad at all----Those people who tout all the films historical errors tis IS a fictionalized account of Lafayette Escadrille how many of the critics especially some of the women critics have even heard of this name before? --Name one WW1 aviation film that has gotten it all correct you can't --"The Blue Max one of my favorites had pilots pulling on some sort of handle to fire their machine guns (all wrong) and had lozenge camouflage on the Fokker Triplanes which was also wrong --there is plenty wrong but I still loved the Blue Max as I love this film too---Maybe director Peter Jackson (King KONG) (who is rumoured considering) remaking the BLUE MAX WILL GET ALL THE SMALL DETAILS RIGHT AND ALSO make a kickass film that even the critics will have to love! Go see FLYBOYS You will be entertained!

This is without a doubt the worst video I have ever watched.The videos picture could not tracted without jumping lines and wiggling screen it was painful for me to watch.The movie itself was out of focus.They used old black and white movies" indians meet the cavalry " to illustrate the action and pencil drawings of the indian chiefs while they spoke of them. There was one man speaking with a monotone voice.After five minutes it became very boring to watch.The movie was put together very poorly and hard to watch the pictures had very little contrast, and hard listen to.It was so bad I could'nt retain any of infomation,my mind kept wandering off. If you enjoy being bored,and having your ears and eyes assulted by this low grade quality picture this movie is for you. Reviewed by Paul Phillips
