Friday was a beautiful, spring day in Windsor, N.S. Under a clear, sunny sky, the Benedict family was doing yard work outside their home when a large hunk of ice mysteriously shattered the rear window of one of their cars.

“I heard this bang -- sounded like a shotgun,” Wes Benedict told CTV Atlantic. “So, when I got to the car, I realized what happened.”

The Benedicts have no idea where the ice came from. Their leading theory is that it fell off a plane flying overhead.

“I could see several pieces, some as big as my fist,” Wes said. “People say airplanes sometimes drop ice.”

Although extremely rare, this is not the first time something like this has happened in Canada. In February, a large piece of ice fell off a WestJet flight and smashed through a Calgary house before coming to rest in its basement. At the time, the Transportation Safety Board of Canada said that it was the second incident of its kind in Canada in the past nine years.

Andrea Benedict, who initially thought her husband was playing a practical joke, is just glad that no one was hurt.

“He was in the car a few minutes prior to that,” she said of their young son, Alexander. “It’s scary because it could have went through the house, it could have hit one of us.”

His two and a half year old son had been in the car only a few minutes earlier. @CTVAtlantic pic.twitter.com/A951p01pQc — Ron Shaw (@RonShawCTV) April 15, 2017
