When I was in Germany an experienced Army Helo pilot walked into the spinning tail rotor of his own UH-1. Everybody has a bad day. The difference is, when I screw up I get ridiculed by my coworkers (it happens frequently); when a pilot screws up it makes national news.
Yeah, it really roasts my 'nads when someone makes yucks at the misfortune of those who sacrifice years or decades of their lives defending them. If a pilot of similar experience wants to bust his chops, then fine. Everyone else should offer to shine his boots.
