you guys spend so much time concerned about uniforms and saluting. *shakes head*
Your choice. In the meantime, I'm working my way through the paperwork and the courses to go up as a mission scanner - figure I can give something back to my community. And it's been a great way to find experienced pilots and ask questions, look for opinions beyond my CFI's. Always to be taken with a grain of salt, but learned a thing or two. Sometimes it's all in having something explained in a slightly different way that makes it go from frustrating to very understandable. Though every bit of advice usually is geared toward being safer, or includes safety anyway.
haven't really seen any signs of any exclusive flying club - they're encouraging folk to fly. As for tennis shoes - the guys that wear flight suits wear boots. Most of us are in meeting in carhartts or other sensible gear - and noting that you always dress for the environment, not the cabin temperature, I can't fathom people wearing sneakers on missions most of the year anyway.
