RE: Destructive inspection...
anted to add my 0.03(inflation). Rules are Rules. You didn't use your pin. Somebody shot you down. The fault is not with the second pilot he followed the rules. He looked at the freq board saw his frequency was clear and powered on. I never fly without putting my pin up. Transmitters used to have flags as well but I havn't dseen them used in years.
By flying without pulling your pin you took a rish. Yes the second pilot should have had common since enough to ask your frequency, but not everbody has common since. You have a right to be mad but be mad at yourself. The freq board is there for a reason.
If you were speeding in a school zone and hit a kid, would it be the kids fault for crossing the street?
Look on the bright side you have an excuse to get the new improved 28% extra. I have seen one and they look awsome.
