MythBusters + cannonball + houses, equals repairs

Posted Dec 7, 2011 by Gar Swaffar
The MythBusters television show didn't achieve the desired results in the latest stunt, but the video shows the route of the errant cannonball and the results might make it to the outtakes segment of the show.

The MythBusters haven't released a statement as of yet, and the tweets of one of the cast, Grant Imahara have been removed regarding just why they shot a house with a cannonball today.
The good news would have been the fact that it was part of a show, the bad news is, it wasn't part of a show and it wasn't done on purpose.
The crew were performing an exercise and shooting at least one cannonball for the show when something went where no cannonball is meant to go these days. Through a house nearby.

According to the Alameda County Sheriff's spokesman J.D. Nelson, the cannonball "took a few unfortunate bounces."
When the cannonball was fired for unknown reasons at a firing range in Dublin, California the extra and errant bounces took the projectile through the wall of a nearby home. After entering the home with very little resistance the cannonball continued through the home and then exited the home, through another wall.
No one was apparently injured in the accident and a picture of the home with a cannonball sized hole is at MSNBC showing the 'exit wound' next to a lighted window.
The cannonball as noted in the video embed, entered the home through the front went through a wall, bounced around for a bit and then left thee home, bounced across Tassajara Rd and hit another homes roof tiles and finally came to rest inside a minivan.
MythBuster's insurance premiums may go up just a bit after this fiasco, although they had been using the old firing range at the Camp Parks Military Reservation for the past eight years.
Perhaps the most difficult to believe happening in this incident is that the resident who's home was first struck, slept through the initial "incoming" attack and was only awakened by the sheetrock dust settling on them.
From the position of the hole in the wall, which is in the second story of the home, the cannonball must have been moving along with a great deal of speed and force. For those of us who enjoy watching things be taken apart destructively and also enjoy unique engineering problems, the show has a great deal of appeal.
