1975 German Grand Prix
This is a great clip from YouTube, this one is courtesy of wippermann. The footage shows what is pretty much a complete lap from the 1975 German F1 GP, featuring Niki Lauda in the lead car. A lot of the film was shot from the air and gives a different insight into the layout of the track. The race was won by Carlos Reutemann in a Brabham-Ford.
Enjoy!
