You couldn't go out the SW gate so people on the westside of the stadium in the donor seats were getting advance word according to a lady that was walking next to us as we went up Asp. We sit in the NE side of the stadium and could see all kinds of flashing lights so we knew something was wrong a long time before anyone around us got a cell phone call.
Cell phones were getting all kinds of busy signals.
Cell phones can detonate some bombs, from what I've read. Don't know how true that is. Is is possible someone had something on to "jam" the signals for a bit while they looked for another device? I'm just speculating.
I live in Norman and go to graduate school in meteorology at OU. I was not at the game tonight, and didn't hear the explosion. I truly hope this was not a terrorist bombing attempt of any sort, partly because I'm concerned about the implications this could have for security and the like.
