24 Hours Of Le Mans 2011 Marked By Two Major Crashes (VIDEO)

Two violent crashes took place on Saturday at the 24 Hours Of Le Mans, one of auto racing's most prestigious events, but the affected drivers seem to have escaped OK. (Scroll down for videos.)

Shortly after the race began this morning, Audi's Allan McNish collided with a slower car and plunged into the outside wall. McNish amazingly walked away from the crash under his own power.

"I'm glad to be alive," McNish said.

The second crash involved Audi driver Mike Rockenfeller after nightfall. Rockenfeller lost control of his vehicle, prompting ambulances, recovery trucks and safety cars to scramble to the scene. Rockenfeller was immediately evaluated but is "OK," according to reports.

The 24 Hours Of Le Mans is the world's oldest sports car endurance race, ran annually in France since 1923, per Yahoo Sports.
