When one removes the said toilet seat condom when does one separate the flappy end from the ring? I was using one just the other day and became concerned if was to tear it from the ring or pray that my "substance" would have the weight to break it from the ring? After a eating a healthy meal at an imitation TocoBell, cause regional pilots cant possibly afford the real one, I was worried that my "substance", which would easily flow through a screen door, would break the paper or if the liquid would be absorbed like a sponge and contaminate the ring leading to skin contamination. Then i thought about the shear force that liquid has when flow is restricted and i was at ease with my decision to leave both ends attached.The challenges we face everyday outside the cockpit are sometimes more risky than actually flying!
I have suffered this cruel fate before. I now punch out the flap every time.
