A strange event took place in Ottawa. Stephanie Moore made a loud noise at night in the former small town of Nepean, which became part of Ottawa in 2001.

When she turned on, she saw a hole in the ceiling and the roof. There were pieces of plasterboard, chipboards and puddles of water on the floor, according to CBC (Canadian Broadcasting Corporation).

The hole in the ceiling had a diameter of about one meter, and was about four feet from the bed where the woman slept.

The roofer who managed the roof, according to the damage, decided that it might be a piece blue ice, dropped out of the aircraft 's biotoil, where the contents of the toilet are mixed with disinfectants.

A piece of ice falling from a great height, which broke through the roof of the house (about 3 km from Ottawa Macdonald-Cartier International Airport), could then simply melt and leave no trace except water. Stephanie used planefinder.net to find out that at the time of the incident, only one DHL plane could fly over her house, which had not yet commented on the incident.

The Canadian Ministry of Transport has also begun to address the event.

Cases of fall blue ice and home damage have been reported earlier. Wikipedia lists similar events that occurred in the UK in 1971, 2007 and 2013; in the USA 2006 and in Germany 2011.

Not all videos in the series have been deleted on the Internet yet myth busters, where they analyzed in detail the destructive power of such "pieces of ice", it is possible to watch it on YouTube.

There may be other causes of ice falling from an airplane. In September 2015, a piece of ice the size of a ball hit a roof and scared residents on one of the homes in Modesto, California, according to Naked Science, referring to the Associated Press.

Jim Mathews of the National Weather Agency in Sacramento assumes that flying planes are to blame for these "incidents."

More specifically, water that is formed in the air as a result of the combustion of aviation fuel. In the sky we can see it as a white condensation trail behind the plane. According to a meteorologist, steam condensate can also form into an lump of ice, which then falls at a speed at which it does not have time to melt in the air.

Experts examining the remnants of the ice also stated that it could not be waste from the aircraft toilet, blue disinfectants were used there and the ice that fell on was clean.

We remind you that strange cases of ice falling from the sky, which did not fall directly from the plane and were completely free of impurities, are not unique, but have been recorded several times.
