[DeTomaso] [EXTERNAL] Gr4 Pantera at Le Mans video

[Mike Drew]

Terry,

When Junior Wilson spun (multiple times) in his big wreck at over 200 mph, on the first half-spin, the wind caught the unlatched decklid, flipped it up and over and smashed it down onto the roof and windshield. The inertia caused it to bend down as it smashed the windshield and because the car was black, he thought he had flipped upside down. He was still upright though, and continued to spin around and around until the car finally left the road and partially buried itself in the desert.
