I built a model of the S-3 Viking back when I was about 13 or so. It came out horrible due to my newbiness at the time, but I have loved that plane for some odd reason ever since I first saw it. And I am glad I could put you out of your misery, alan

Edit: Actually, i am not German, although I do speak it and have been there a few times. Literally it means "go silent". I first heard it before I learned German playing a computer game called Silent Hunter III (a very good submarine game based on WWII German U-boats).
