Fascinating video of 1955 Belgian Grand Prix

Thanks to a tip from Nigel Roebuck at Motorsport Magazine, race fans are discovering a fascinating 30-minute documentary on the 1955 Belgian Grand Prix that takes viewers back to a much simpler time when speed and safety were completely different goals. 

You'll want to watch the entire clip -- which Shell funded at great expense given the number of cameramen and crew -- to see legends like Fangio and Moss muscle their way around the grandest of racing circuits, Spa Francochamps. It's scary to see how close cars at high speed get to nonchalant pit crews and observers.
