Can anyone tell me why a Bell 47 Helicopter appears in the film â Where Eagles Dare â ? The whole sequence seems pointless and ruins the film. Im right in thinking that no Helicopter design was ever produced during the war? ....... and also ( ranting now ) How may sticks of blerdy TNT can you get in a small daysack.Clint & Ritchie seem to have a never ending supply. Rant over.
