London: A retired British couple were left with a hole in their roof after a chunk of frozen poo and urine reportedly fell from a passing plane, media reports said.
Keith Mead, 70, and his wife Ruth, 67, heard a loud bang and rushed outside thinking there had been a car accident.
But they were surprised when they saw a hole in their roof and found the seven-inch long chunk of ice on the lawn.
The lump of frozen urine and faeces, which was seven inches long and weight more than a pound, had fallen from a jet about 30,000 feet overhead after being flushed from a toilet on the plane, they claim.
Mead bagged up the ice ball and put it in his freezer to show insurance assessors who visited that day.
"It was just as if someone had crashed into our house. I looked up and there was a gaping hole where a large lump of ice had impacted the roof," he said.
"Thank goodness it didn't hit anyone. It could have killed them," he said.
The couple fear the repair bill will cost 1,000 pounds because the poo ball also ripped the roof felting.
According to British Civil Aviation Authority, incidents like this are rare. A spokesman said that of the 2.5 million flights a year over UK airspace, around 25 ice falls are reported annually.
