While it's a fine line between being part of the "flying culture" and being ridiculous, I actually like that some non-flying parts of the AF have adopted flying community terminology. What a concept, maybe we can built the Air Force culture around, ya know, flying instead of bullshit and paperwork. Think of that next time some shoe talks about wingman or a satellite dude gets a checkride...that's your opportunity to impart on them that specific piece of Air Force flying culture.
On topic...getting rid of space flight suits makes sense for Gen. North's reason #1 (their duties do not require it), but not so much from reason #2 (same uniform = one team, this is the dumb reason IMHO why O-6 pilots don't wear flight suits to work) and reason #3 (cost savings...see Toro's post).
