Rain and lightning lashed Germany Thursday, and a man was killed when a circus-tent collapsed at a rock festival in the south of the country. Frankfurt International Airport cancelled 44 take-offs and 11 landings because of storm danger, an airport spokesman said, and 30 incoming flights were diverted to other airports. Some take-offs were delayed up to an hour as pilots waited for scarce departure time-slots, the news agency DPA reported. A summer storm killed a man Wednesday while he was strawberry picking near Cologne, and a first-aid official was killed Thursday at the Southside Festival near the small south-western town of Neuhausen ob Eck.
