P.S. Simple Math

The question is where is the documented evidence of any witness stating they heard an ear shattering roar and saw a flash of light from the GK, prior to hearing any shots. It stretches credulity to believe that they would remember hearing a firecracker but forget an ear shattering roar. Unless there were some Men in Black at work on the GK that day.
