A big impact for Anders Fjordbach of the #20 High Class Racing team turned strategies on their heads as the full course yellow was called for.
The Dane lost control of his car part-way through the Le Mans 'double' chicane, a tricky left-right-right-left sequence.
He was able to walk away from the crash but he, alongside teammates including former IndyCar racer Ed Jones and former GP2 racer Raffaele Marciello, are now out of the event.
At the time, the lead car was the #60 Acura car, being driven by Simon Pagenaud.
