What happened: Authorities in Australia claimed on Thursday that strong winds carried an inflated jumping castle into the air during end-of-year school celebrations at Hill Crest Primary School. This led children to fall from 33 feet, killing four of them and injuring several others. Details: The jumping castle’s ascent into the air is currently inexplicable. The students were in Grade 6, the final year of primary school and were 10-11 years old. Around 10 a.m, two boys and two girls in their final year of elementary school died in this accident at Devonport. Authorities reported five more youngsters were in the hospital and four of them were in severe condition. More: Authorities say that this tragedy would go down in Australian history as one of the ‘deadliest’ involving an amusement ride. “We’re all mourning their death on a day when these children were supposed to be celebrating their last day of elementary school,” says Tasmania Police Commissioner Darren Hine.
