For those in Vegas, there still is some Red Bull on-track activity this weekend. Today prior to the Busch Series start, the Red Bull Air Force skydiving team jumped into LVMS in their typical fast moving, swirling and swooping fashion. Tomorrow Red Bull's BO-105 CBS aerobatic helicopter piloted by Chuck Aaron performs aerobatic stunts for the crowd prior to the race start. While we all would prefer to see the No. 83 and No. 84 on-track activity, these amazing professionals in the air are a sight to see.
