Mattias, who is thankfully back to signing his comments (T-Blt, you need not worry anymore), dropped a link to a gallery of historic shots of the Silberfeile (Silver Arrows). It starts off totally awesome and gets really, really creepy. It's strange to think of all of the incredible engineering feats that came out of the Third Reich while watching a man incite so many to hatred, bloodshed and depravity. It's definitely worth a look.
