Anyone can explain hitting the pipe with the pointy side of the hammer?
Can someone with some knowledge of submarines explain why the guy was hitting the pipe in the control room of u571 with a hammer? And more specifically, why the hell was he using the pointy side?
To refresh, its the scene where he is going along the pipe, hitting it (fairly softly) every foot or so. He hits a rusted spot and the hammer goes right through and the captain tells him to put a pipe patch on it.
Every time I watch this movie I scratch my head on that. I am sure there is some kind of reason they do this, and would love to know.
