This makes no sense. There is only one way to measure cost. The amount of money required to be spent because you own and operate a specific thing. You can either include gas, insurance, depreciation, mx, etc., or you can lie and not include it all. Also, the AF is different than owning a car. If you don't own a car, your taxes for road construction and DMV workers are not going to go down. If the AF BRACs a base, guess what, they don't have to pay for workers at the MPF, they don't have to buy towels, they don't have to pay for more pea gravel at the CDC playground. The AF's support bubble goes out a little farther and is a lot more direct than you buying a car.
I think everything should be included in the price per flying hour. If it takes 500 man-hrs on mx per flight-hr, why should that not be included if a similar plane does the same job on 50 man-hrs. Likewise, having 300 people in the squadron requires more money for everything from salaries to flu mist vaccinations for dependents to PFT waist measurement tapes. Otherwise, what do you attribute that cost to? Tops in Blue? I hope so, because I'd pay anything to see them again....
