Answer 1

You read the article on Cnn, the piece that went through the roof on a New Jersey home.
What's his name that told you to "Use your head" well, I have news for him: a friend that was working on a power line in Northern Minnesota in 1978 was sitting in the cab of his truck taking a break. A man running a huge commercial wood chipper following these guys cutting the trees, the chipper hit a huge rock, two blades broke and went flying, one went over a measured 600 feet, better than a city block through the woods, or over them I should say. Coming down with a force that it went through the cab of the truck and hit the guy in the head, taking off the top of his head and burying itself deep into the dashboard of the truck.

It should be in the Duluth Tribune news for that year, he can look for it, I know his son well.

Answer 2

stop and use your brains. no wood chipper can do that kind of damage even if it was spit out. That chink of metal was from some explosion. It was driven through the guys roof, down through the wood structire, and was wedged ware the dudes walls and ceiling came togeather.

If you totaly beleive what the news media is trying to hand you, it's time for a mental check up.
