i grow up outside of naila germany ( where they land ) and every detail of the film be 100 % authentic and the power line that they fly over and the nosy neighbor and the grandmother tell the kid that they cant watch west german tv and etc . this movie bring back lot of good memory to those that be european and a great production from disney . the same movie in german have klaus lowitsch and gunter meisner use their own voice for translate the english version into german . for the german version they also use cookoo bird and a bird that be native to germany a background noise to let you know that you be in germany . i show this move to many of my german relative and they really like this movie . ( these people make make a prototype balloon which they have to give up because the material that they use be too porous and the other 2 balloon that they use for the escape . the burner problem be solve when they turn the propane cylinder upside down . ) .
