“I have seen at Hill AFB, UT the multi-acre under one roof C-130 rebuild facility! The C-130’s are taken apart to every bolt and nut. These C-130’s are “new” when they leave Hill AFB, air frames and engines! Age of a particular C-130 after they went thru Hill, AFB rebuild is of no concern.
Now that said: Has this C-130 been to Hill AFB for rebuild?”
This C-130 was on its last flight into retirement when it crashed. Does not sound likely to have been sent in for refurbishment of any kind.
