It is obvious that someone, somewhere, was the first person to relieve themselves in an aircraft. Who was this urinary pioneer? — history does not record,” Why are there so few facts recorded about early aircraft toilets?
Over the years air travellers have argued over questions like ‘is the waste flushed out of the plane mid-air?’ and ‘can the door open from the outside?’ Aeroplane toilets have been the subject of much debate and rumour over the years. Here are some facts you should know.
Aeroplane toilets are called vacuum toilets
– because they use an active vacuum instead of a passive siphon like your usual home toilet. When you flush, it opens a valve in the sewer line, and the vacuum in the line sucks the contents out of the bowl and into a tank. Because the vacuum does all the work, it takes very little water (or the blue sanitizing liquid used in aeroplanes) to clean the bowl for the next person.
It turns out that vacuum toilets have lots of advantages, even for normal installations. A list from Science.howstuffworks.com webpage includes its ability to use little water and a much smaller diameter sewer pipes. They can flush in any direction and can be put anywhere in a building.
That it is a toilet does not mean it is the dirtiest place in an aeroplane
Fold-down tray tables contains more germs. New toilet systems in aircrafts can be self-cleaning with Boeing using UV light technology that sanitizes all surfaces in three seconds.
The toilet in an aeroplane sucks you in if you flush while sitting down.
You can get stuck if your body forms a perfect seal on the toilet seal. It is a good idea to stand before flushing.
The waste from an aeroplane’s toilet is not dropped from the sky
-They are stored away and later sucked out by a vacuum. Some people say the waste is flushed out through the sky while flying but it is not so as this may cause a change in the pressure that can block your ears
However, “A man in California once won a lawsuit after pieces of “blue ice” fell from a plane and came crashing through the skylight of his sailboat,” said Captain Patrick Smith, a pilot and author of Cockpit Confidential. What happened was that “A leak, extending from a toilet’s exterior nozzle fitting, caused runoff to freeze, build, and then drop like a neon ice bomb” he explained.
