Airman 1st Class Jeffter Louzada, 364th Training Squadron cables and antenna systems apprentice course student, climbs out of a manhole with the assistance of Airman Noah Carbonaro. The manhole was in between two other manholes so a sheave and shackle had to be used that allows them to run cable through conduit and make a 90 degree turn.
