I worked F16s...I can believe that a technician performed crappy maintenance and caused the failure.
But I'm not buying that there's much else one can expect to accomplish with regards to updating manuals.
Same basic design has been flying for 40+ years and now it's insufficient?
One has to make a deliberate physical maneuver, a cock of the wrist to get the throttle past a hard detent/stop to go from Idle to OFF...something smells.
