A 69-year-old man in England stepped out for a bit of exercise Friday morning only to return to discover a hole in his roof and ice chunks scattered about.
Wahram Manoukian of Oakley Green village was none too happy.
"When I discovered it was ice I was shocked," he told the Daily Mail. "It had bounced off my roof and then smashed through my garage roof, the ice and tiles just smashed straight through.
"I was fuming. My grandchildren could have been in, as they come around after school and during the weekends they come around to us.
"Fortunately my wife was out too. I could have been killed. It could have been anyone.
"The force must have been astonishing and would have killed anyone instantly."
The ice block weighed at least 21 pounds, which was the weight of the ice chunks he had collected.
Manoukian phoned the Civil Aviation Authority hoping for an investigation as to where the ice block originated. He suspected it was from a passing airplane. The CAA says ice can form on an airplane at high altitudes and fall off when it descends to a warmer height, but it's "relatively rare," the Maindenhead Advertister reported.
The CAA logged the incident but doesn't plan to investigate. It directed Manoukian to the CAA website where it had this statement:
"As the safety regulator for UK civil aviation, the CAA requires UK aircraft operators to minimize the risk of ice falls by performing regular maintenance to prevent leaks and take prompt corrective action if a defect is found.
"The CAA is unable to investigate the potential origin of an ice fall, but does record reports of this nature.
"Falling ice which is clear and uncontaminated may not have originated from aviation activity.
"Indeed there have been reports of falling chunks of ice which date back to before the existence of aircraft.
"Research into the phenomena is ongoing by scientists across the world but is controversial."
