I see this happen everyday as a 17 year DOD employee working for the Air Force. Examples: Propellers for all the C-130 gunships have to be sent back to the manufacture for rpair or parts replacement. Brand new engine/repair facility on base. Can remove props. but not repair. Some CONTRACTORS on base AF personnel can't work on. A constant stream of independent truckers picking up and delivering Props. Same goes for the Rolls Royce engines. Some contractors on site to repair, but most shipped to manufacturer using contract truckers/not military transport. Now you may think that's the way of the world today and it is. This needs to be changed in order to save you/me our tax dollars. Understand these C-130's are the entire fleet/base of the "SPOOKY" gunships which are always in the fight. At another AF base 30 miles away is the home of the F-35 fighter training program. Do you really think the AF maintenance personnel work on those aircraft????? There are 1000's of contractors doing the work at our expense. Another reason why the retention rate is so low. These Airman/women get frustrated and bored because they aren't doing what they were trained for. So they put in there time and go to work for the contractors doing their jobs, plus a huge raise in money within the civilian world. I guess in a way this makes me a Whistleblower. Problem is it's all part of the DS and AND GOES TO THE VERY TOP. Problem is  "NO ONE GIVES A SHIT"
