i consider this movie definately not to be worth watching for the second time.. too much cliches, no suprises and predictable in so many ways.. it's like the old and overused scenario of boys becoming men, performing some acts of heroism, losing of friends and getting even with the enemy, falling in love, one overcoming a mental obstacle, one last fight against the supervillain and of course the rascal become the hero .. i could go on and on.. and just put it into new enviroment, which in this case was WWI and the Lafayette Escadrille.
about the air figths - bullets slashing the canvas behind the pilots back and nothing happens to the pilot.. the wind seemed quite mild so high up in the sky and the planes so perfectly under control
