Mystery object leaves big crater

A mysterious object that dropped out of the sky puzzled residents in the rural town of Bridgewater in Victoria, Australia.

The impact created a big crater that was filled with scraps of metal and circuit boards.

Speculation over the object ranged from helicopter debris to UFOs.

But it has been identified as a parachute experiment gone wrong.

The parachute, weighing about a ton, malfunctioned and fell to the ground.

Although there was no explosion, it left a big hole and killed a field mouse.

The hole has now been filled.
