The grass is always greener on the other side. But, it's pretty green right now on this side, looking from this side too. But the key word is "NOW". Who knows what the future holds?

I'm purple (feel like silver), not brown but I wouldn't suggest it. Try some obscure management job, safety, research, tech pilot, test pilot, or something within SWA - as long as you know you can get back to the line later.
