What Mel Brooks movie is this?

A friend mentioned a movie to me by Mel Brooks where he is a jew and is trying to help them escape the nazi’s in germany during WW2 and at one point in the film he dresses up like hitler and all the jews get in a plane that crashes in england with mel brooks still dressed up as hitler. I would like to get this movie for that friend because he mentioned how much he loves it and how he cant find it anywhere. He couldnt remember the name of it and I was lost on google. Anyone have a clue what the name might be?? (i even tried IMDB but he has soooo many movies that he directed/acted/produced so i gave up after a half hour of searching)
