Thanks for your responses fellas, it turns out my buddy was in shock, the ems took good care of him, he is in the hospital for observations because of the head trama but looks like nothing major is wrong, just pretty banged up.
Apparently he looked worse then he was, I was just shaken up seeing and hearing him in pain. I talked to a few people from our group last night, we all agree it was just an unfortunate accident, no one did anything to cause the crash. We'll be riding as usual this weekend.
Thanks again.
