I did a flyby for NASCAR one time. I was pretty impressed how well the promoter handled all the coordination. He had an AF ALO come down with all his radios to act as the FAC. He also had his own guy sing the national anthem. He told us in the prebrief his singer could vary the length of the song by a minute. Thus he would give us a TOT 4 minutes prior and then use the singer to adjust for changes. Pretty hard to screw this one up. Those NASCAR guys really had their sh!t together.
