Life Support
OFFUTT AIR FORCE BASE, Neb. -- Airman 1st Class Rebecca Wheeler, an aircrew flight equipment technician with the 55th Operations Support Squadron, uses the simulated Scot Tester to perform a fit test with a HGU-55P (flyer's helmet) on Airman Devin Williams, also an aircrew flight equipment technician with the 55th OSS, while Airman 1st Class Steven Cunningham, 55th OSS, looks on. The Scot Tester pre-flight procedures insure equipment is tested for normal and high altitudes before aircrews here deploy. U.S. Air Force Photo by Kendra Williams
