Time for a fun poll !!
After reading the intriguing and in some cases amusing quotes (below) from this thread, which was on a different topic, I thought it would be interesting to share opinions of why you will, or will not take a dump on the 37,000 foot throne. Aside from the quotes, I guess I should state my own opinion: I have had no problem with this on several flights. In fact, I have found most airplane lavatories to be much cleaner than the airport bathrooms, and usually have better toilet paper too. When I find the toilets in the airport to be a mess, I will wait to use the toilet on the airplane. Something to do during the flight anyway...
I still love aviation, the wonder of it, I still have those small moments when I'm on the toilet in an airplane and it just amazes me that I'm taking a dump while going at near trans-sonic speeds high in the troposphere
You take a dump on the plane? I have to have a major case of the runs to take a dump on a a/c toilet, even in F!
On a long haul flight which is not full and the toilets are clean? No problem whatsoever, when you gotta go, you gotta go.
I'm with Coal on that one. Pooing on planes is nasty. Get it out of your system before you fly. I've had to go into a toilet after someone who had been for a crap too many times and thats just nasty. I'd hate the idea that anyone would be queuing up to go in after me and have to live with it. Urgh. I am 99% sure I've never had a poo on a plane ever in my life and thats in 323 flights including some very, very long ones. (17 hours DOH-IAH is prob the longest and I didnt even then, and the cabin only had a dozen or so other pax!).
I do all the time.... It isn't any nastier than taking a dump at the airport. I would say more people crap at the airport than in the air. The only thing I don't like about using the john on the plane is that I know other people are waiting and I need to hurry up, so I can't relax and read my newspaper.
