I'm primarily a glider flier, and it goes without saying that they're extremely prone to going permanently AWOL. Maybe because I put so much time into carefully airfoiling, balancing, trimming, tissuing, and "decorating" for visibility, watching my first two "masterpieces" soar off on thermals was...well, maybe not all out traumatizing, but it sure turned my day into a downer. My only consolation was imagining whoever found them would be stoked and give them a good home. Now 3 years in and 7 gliders fewer, I've become a bit more numb and accepting when it happens (though that silly little kid inside still insists on getting all teary).
