There are a few obvious caveats to my observations, not the least of which is that I'm just getting my feet wet in the AF. That said, another point to consider is that the AF is a considerably larger organization than the MC with a much larger array of communities. I expect that my experiences in the AF will be quite distinct from, say, someone flying for the mobility command. That's what makes my skin crawl when people make sweeping generalizations about any of the services - I wouldn't pretend to know any more about life in the F-15 community than I would the Marine EA-6 community, cause I've spent no time in either. Best I can do is offer observations based on my own experiences.
Case in point though to support my earlier contention that flying in the AF isn't as suffocating as it's made out to be...we have T-38's in the squadron that constitute our Companion Trainer Program. Once you're checked out in it you can get on the schedule for an out-and-in (or out-and-back in AF speak), which means that you get a jet for the day to fly pretty much where ever you want to go with it. No flight plan needs to be submitted in advance to the command, no formal screening of your plan. It's on you to make sure that you you don't go into a field you can't get back out of or land someplace that can't get you started - which basically means it's on you to be the winged aviator that you are. Just take off when you're supposed to and get back at a reasonable time. Want to head to Yuma to see some buds and have a Bunker Buster at the tower? Go for it. Want to head to Seattle for lunch? Go for it.
You've basically earned the trust of the program to not do anything stupid. Of course, pork it away and you can expect to stand tall when you get back, but they give you the rope to hang yourself. Once again we're comparing apples to oranges, but the notion of just heading out with a Harrier and a gas card in that manner for the day is beyond absurd (again, on the east coast, under the regimes I experienced) - out-and-ins were deliberately scheduled and command approved. Different jet, different everything really, but my original point stands...you can't categorically say that naval aviation is more free wheeling than AF aviation.
I'll save my observations thus far on the distinctions between leadership in the AF and the MC for another dissertation...
