A Chicago man came home to his Ravenswood apartment Tuesday to find three chunks of ice the size of bowling balls crashed through the ceiling of his living room.

John Connors, an IT specialist, said the ice mass must have plowed through his roof and shattered on impact because he later discovered four large pieces of debris in his bedroom, 15 feet away.

“I don’t know how fast thing was going to go through my roof,” Connors said. “But it shattered a ceiling beam and came down here."

Neighbor Doris Patitz said she was at home around lunchtime Tuesday when she heard a loud bang.

“I got dressed quick and ran downstairs,” Patitz said. “I thought a house blew up on the neighborhood.”

The only witness of the event was Connors’ petrified cat.

"When I looked up I saw the sky and a plane fly over," Connors said of his new living room view. "It was just a disaster in here, like a bomb went off.”

Where the blasts of ice came from remains unknown, but some think the answer could lie in the planes flying overhead that Connors can now see firsthand.

Until the mystery is solved he is keeping the ice chunks in his freezer next to his frozen food as a momento of the disastrous event.
