27. Pull the inner mid, outer mid, and fly boom sections out
of the base boom section. Use additional lifting devices
and reposition any lifting straps as necessary as the sec-
tions are withdrawn. It will be helpful during this step to
pull the outer mid retract cable out from the front of the
base section as the other sections are being pulled out.
This will prevent the cables from tangling as the sections
are withdrawn.
