Fifty-one concertgoers were hurt and nine sustained serious injuries when a single lightning bolt struck a mast at the eastern German festival With Full Force Saturday night.According to Spiegel Online, the lightning strikes sent some music fans flying through the air — and left behind a wasteland of destroyed tents, panicked guests and a venue flooded with mud and deep puddles. "The first showers, heavy as they were, provided just an inkling of what was to come," the site describes. "Just before 2 a.m., the next black cloud parked over the stage. And the lightning it unloaded resulted in 51 injuries, three of them landing in the intensive care unit of a nearby hospital." Emergency services spent several hours at the scene treating those who had been sheltering in a cocktail bar near where the lightning struck, The Local reports. With Full Force annually attracts tens of thousands of visitors in the town of Roitzschjora near Leipzig. This year, bands like SOULFLY, MACHINE HEAD, FLOGGING MOLLY and PENNYWISE performed at the event.
