Inspection to perfection
U.S. Air Force Senior Airman Thomas Cadwell, an aircrew flight equipment technician assigned to the 509th Opera-tions Support Squadron, inspects the oxygen bottle at-tached to a parachute at Whiteman Air Force Base, Mo., Aug. 21, 2017. If a pilot ejects at a high altitude with less oxygen, he will need to pull the oxygen bottle cord which will release oxygen through a tube connected to his helmet.
