One of the desert nights included an arival & departure "desert drag". This was a test of acceleration, stop, acceleration & final stop. We beat most at this, except for the 911 Porsche. Another 911 broke a drive shaft on the same test but fixed it overnight. The Austin Atlantic broke a half shaft departing the final desert camp. The support vehicle welded it & it lasted until 20 minutes before Cairo when it broke again. They were towed through the finsh line.
