Maybe it's an extraterrestrial hole-in-one? A huge ball of ice fell from the sky above Victoria, Australia, smashing into the fifth hoe green at the Belvoir Park Golf Club. It left an eight-inch deep divot in the grass. Shards of ice were found as far as 160 feet away from the impact spot.
"Where's it come from? The conclusion we've got is that it's fallen from an airplane, we guess," [golf club superintendent Dylan] Knight told the Australian Broadcasting Corp[…]
Ice balls that fall from airplanes are known as megacryometeors and have been known to impact the ground several times a year. Aviation expert Geoffrey Thomas said de-icing technology used on commercial planes is meant to cause the ice to melt before it hits the ground.
"It is exceedingly rare for a piece of ice to actually hit anybody. In fact I've never heard of it. But that is not to say it hasn't happened," he said.
