Apparently on an OU Fan Message Board the original poster posted a the thread saying he lived about 1 mile west of I-35 and heard a loud explosion. He wanted to know if anyone else heard, or knew of anything. Follow-up reports from KOCO Ch. 5 news related by other posters stated the explosion occurred in Choctaw. As of this time I'm unable to find reports of this in the local media.
I watched Channel 5 after the Football Game and they cannot find anything. They broke into the game with the news. There is no way that they could have heard this in West Norman. Maybe in way East Norman north of Lake Thunderbird but that is at least 10 miles from where I live east.
Was at the computer when they broke in the game and my windows did not rattle at all and they definitely rattled and I heard the explosion the other Sunday night.
We are 30+ miles away from Choctaw and that school.
