A chunk of ice crashed through the roof of a Calgary home on Friday night, Calgary Fire Department officials say.

The piece of ice — about 30 centimetres across — hit a bungalow in the 100-block of Doverthorn Bay S.E.

"It had gone through the roof, through the ceiling and into the basement," said Battalion chief Paul LeBlanc. "We determined it to be a piece of ice that fell from an overhead plane that was passing by."

The fire department has contacted the Calgary Airport Authority.

"Fortunately, no one was hurt. Other than being very scared at the time, the occupants are doing just fine."

In 2008, the Transportation Safety Board concluded that ice that crashed through the roof of a Calgary woman's home had come from an airplane flying overhead.
