Mythbusters cannonball accidentally goes through house, hits car

A cannonball fired by the Mythbusters went through a house, across a road, and into a car, but the accident injured no one.

A 5.5 inch cannonball fired from the Alameda County Sheriff’s Department bomb range in Dublin, California, “went through the house while the occupants were asleep, then exited the structure and bounced across Tassajara and into a parked car, breaking its glass and landing inside the vehicle,” Dubiln’s Patch reports. It has photos of the damage.

A sheriff’s department spokesperson told media that the cannonball, fired out of a cannon used on the show before at a range they’ve used more than 50 times, “took a very unfortunate bounce that sent the ball skyward and out of the range.” Discovery explained the incident in a statement that said, in part:

“During the testing, a cannonball took an unforeseen bounce from a safety berm. No injuries were reported, but damage was reported in one Dublin home and one parked car. Sgt. J.D. Nelson, Public Information Officer and bomb technician for the Alameda County Sheriff’s office, who is a regular safety explosives expert for MythBusters, was on site and all proper safety protocol was observed. Beyond Productions is currently assessing the situation and working with those whose property was affected.”
