Tech. Sgt. Ken Jones installs a new heat exhaust boot in the air conditioner compartment of a C-17 here June 1. The exhaust boot required replacement after the previous boot was severely torn, causing an air flow leak and disabling of the air pre-cooling system. Sergeant Jones is an electrical and environmental specialist with the 315th Maintenance Squadron. (U.S. Air Force photo/Staff Sgt. Daniel Bowles)
