Because my butt is covered in a very thick fur, I thought that I could maintain containment, so I got in the front seat of my 2-32 and proceeded with my take off check list. As I closed and locked the canopy, I tested the air for any evidence of my leakage. So far I think I'm safe. Take off was smooth, but I was surprised at how hard it was to concentrate on my flying. I was distracted and I could feel the containment plan failing, but the ride was uneventful and the landing was ok. During the exit from the plane I was careful to keep the passerger in front of me. My house is right across the street from the airport so I was able to shower and change before the next ride. Never trust a fart!
