Well, If I failed a check ride...
I guarantee I'd pass the second time -- or shoot myself.
I was crushed when I got 86% on my instrument written-- seriously I was in a bad mood all day, my Instrument checkride got a bit hairy on my ILS thanks to The summer updrafts in Pueblo, but I made it and didn't get a pink slip.
I hope I never have the misfortune to fail any checkride, but if I do, I don't think my firstr question would be to find a different examiner.
