Well they crash millions of dollars worth of equipment and somehow at the end of the artical it gets to us lowly RC fliers as being a big problem. I went to a local RC club to watch a helicopter demo and learned a great deal about safety, doing what's right and buying insurance ect from a lot of friendly long time fliers. Be careful out there people. Don't go it alone check in with your local RC club if you are a newbie like me.
