It's, 9:02 AM, an explosion rings throughout the Alfred P. Murrah building, it's the beginning of the worst bombing on American soil before 9/11. The blast was strong enough to vaporize half the 9 story building. The bomb was named a fertilizer bomb because of the use of ammonium nitrate which is in fertilizer and used fuel oil. The explosives were like a shaped charge in the form of a J to explode toward the building. There was no legit security on the Murrah Building also other federal buildings didn't have any. This is going to show you what the OKC bombing did to our nation. This was a wake up that would never let the US go back to sleep.
