It is a myth that airplanes dump poop from the toilets when in mid air. The waste is securely stored in a tank and is later cleaned out when the airplane gets ready for the next flight. However, there have been incidents where poop and pee have leaked out of airplanes and fallen out of the sky in the forms of large clumps called blue ice.
In order to know how airplanes clean their toilets, watch the videos below. But before you watch how they are cleaned, you should know how airplane toilets work. Unlike conventional toilets at home or down on earth work where water flushes down the waste, airlines use little water and a powerful vacuum to suck the dump into a large secure tank.
