Lockheed Martin maintenance contractors pull the generator cable way from an MC-130J prior to a mission at Eglin Air Force Base, Fla. The test aircraft has been fitted with vertical fins on each wing, called winglets.  The 413th Flight Test Squadron aircrew and engineers tested the modified aircraft over eight flights.  The goal of the tests was to collect data on possible fuel efficiency improvements and performance with the winglets and lift distribution control system installed.
