While I am waiting for a link on Bloomberg or through Reuters. I did some research for those that do not think shit like this can actually happen.
Over the past decade, over fifty such objects have been recorded worldwide. Some have been as small as about one pound, but one monstrous mass of ice that fell in Brazil weighed about 400 pounds– almost a quarter of a ton– and crashed through the roof of a Mercedes-Benz factory. One recently made headlines in Oakland, California, weighing over 200 pounds and creating a dent in the Earth three feet deep. A similar event occurred in Chicago last February, crashing through the roof of a house.
