At approximately 5h23m of the 6 hour race car #20, a Porsche 919 hybrid Le Mans LPM-1 lost control at the beginning of the start-finish straight and collided with a Ferrari 458 GTam and the outer guardrail. The Porsche crossed the track impacting the inner guardrail. It then slid for about 5s and 100+ meters more coming to rest in front of me. Porsche driver was Mark Webber. Ferrari driver was Matheo Cressoni. Both spent the night in the hospital. Cressini was released Monday. Webber was remainded under observation because of concussion. Webber had an accident in a Jaguar F-1 car in 2003 at nearly the same location. I have posted 30 Photos of the accident in my FB page. Name James Wattengel.
