Have you ever wondered on what happens to your poop when you go to toilet in the airplane?

After pooping in the airplane, after you must have flushed the toilet, you will hear a sound, which some may think that the sound is due to the faeces is exiting the plane. No it is not so.

Actually what happens then is that when you must have flushed the toilet, the waste travel through the pipe connecting the lavatory and tank at the rear of the plane.

However, note that the tank can only be accessible only from the exterior of the plane and the waste is not gotten of during the flight, but it being emptied from the tank when the pilot had safely landed the plane

Emptying the tank is carried out by special service truck, where a hose is connected to the tank and the truck sucks out all the waste and after all the waste must have been removed, the tank is then disinfected
