Guys, Have you ever used the toilet on the plane? If ever, surely you wonder where it all ends. To answer your curiosity, you should read my simple writing.
The toilet system in a modern aircraft was invented by James Kemper in the 1970s. Prior to that, the passengers of the aircraft had tossed on some sort of bucket in the bathroom during the plane. The Kemper vacuum system was first used on Boeing aircraft in 1982. The system relies on a blue liquid known as Skykem-a non-stick coating, and vacuum suction.
When you press the flush button, the valve at the bottom of the toilet bowl opens and enters the pneumatic vacuum. The toilet vacuum stirs its contents and stores all the collected waste. The blue liquid is the "closed waste system".
However, contrary to popular belief, the aircraft captain does not have the ability to take off the toilet tank and throw it in the middle of the flight.
"It is impossible to remove dirt from the toilet during an airplane. Just when the plane lands at the destination airport, the blue liquid and dirt in the toilet is sucked up by a dirt truck and thrown in its place." explains Patrick Smith, a pilot and author of Secret Cockpit.
If the tank in the plane is full
When someone reports a "blue ice" that falls from the top, it is usually due to leakage of a waste tank or a frozen exhaust tube onto an airplane.
At the end of the flight, the toilet contents are moved to another tank behind a truck. Once the tank in the plane is full, then the waste is taken airport. And by the airport tanker's waste officer was brought to a special shelter.
There are indeed some cases of tank leaks that have occurred, and usually falling down it is a frozen blue liquid because of the cold temperatures in the sky to make the disinfecting liquid feces that are frozen so that it is called a blue crystal.
