There was a dress code? Huh. Who knew.
I guess I'll throw my two cents into the debate. I can't say one way or another if IFS helped or not. I was one of the first guys to go through Mobile. On the plus side, it was nice not being completely lost when it came to radio comms, and having a frame of reference when it came to knowing where most of the airports in area 1 (maybe I'm confusing it with area 2, which ever one was on the east side of Mobile bay) were. It was also a hell of a lot of fun. Other than that, IFS did not help all that much when it came to monkey skills, military comms, or emergency procedures. In fact, I remember sitting around in primary with a bunch of other students marveling at the fact that our "emergency procedures" were something to the effect of land on a runway or land someplace that isn't a house or tree.
From my point of view the intent of IFS is simply a way to wash out people who discover they aren't comfortable in the aviation environment, whether that be by natural selection or self selection. Nothing more, nothing less. Anything taken away from it is simply (minimal) icing on the cake. Wether or not IFS proves to provide the economic savings the Navy hopes, I don't know. If it turns out IFS saves no money for the Navy I see no point in it continuing to exist.
