Airplane Lavatory Myth?

Wow, that's a popular airline in Asia. A nice plane but have you all wonder how the airplane dispose the lavatory waste? First of all, for those who don't know what a lavatory is, lavatory is also the toilet in an airplane. For many years, I have the idea that the wastes(shit/urine) goes out of the plane just like what a bird does. Haha.

I later found out that it doesn't work that way because if it were like that, then there will be many innocent people becoming their victims, LOL. Imagine there is a piece of shit flying from 10 thousand feet above with the acceleration of 9.81ms-2 hitting you on the head. You will feel that you are really lucky....

Here's a look at the lavatory in the airplane.

Looks small isn't it? I cant imagine how do fat people fit into this small room. But so far, I haven't hear of anyone getting stuck in the airplane lavatory, and you guys think that it's easy to get stuck inside that tiny toilet, do you know how hard is it to make yourself to 300kg?? lol, no offence to the obese people ya ^^ Peace :-)

Ok, but there are some differences between toilets in the airplane and on ground. There is no water in the toilet bowl because if there were water int he toilet bowl the water would splash out every time a little turbulence came along, you wouldn't want that wouldn't you? A free wash on you, lol. Airplane toilets use an active vacuum instead of a passive siphon, it's called the vacuum toilet. When you flush, it opens a valve in the sewer line, and the vacuum in the line sucks the content out of the bowl and into the tank. This happens during the flight. The wastes are collected into a tank, and it is only disposed after the plane has landed. 

Another thing to remind is that DO NOT smoke in the airplane lavatory, do you all know how much non smokers hate the smell of the smoke in the lavatory or toilets!!!! It really sucks.. Ok, I think that clarifies the myth about whether the plane disposes human wastes on flight like birds do. So ,the next time you got hit by something that looks or smells something like a shit, it is definitely bird shit and it must be your lucky day, LOL!!!
