Dylan Knight, superintendent at the Belvoir Park Golf Club, said he was called to the fifth hole green about 7 a.m. Tuesday on a report of large chunks of ice littering the area. Advertisement Knight said he initially suspected the course's sprinklers had gone off overnight and frozen, but he arrived to find a giant ball of ice had apparently crashed down onto the ground and exploded into smaller pieces spread out as far as 160 feet. He said the impact left a sizable dent in the ground, indicating the ice ball had fallen a considerable distance out of the sky. "Where's it come from? The conclusion we've got is that it's fallen from an airplane, we guess," Knight told the Australian Broadcasting Corp. He said the ball left a dent 8 inches deep. 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.

Knight said repairs to the green were being planned for Tuesday afternoon and Wednesday.
