On November 16, 2003, Sina News reported a somewhat embarrassing news that at about 16:00 on November 12, villagers in Longwangtou Village, Niulanshan Town, Shunyi District, Beijing, suddenly heard a loud noise, and the garage built by farmer Zhang Mou's family with asbestos tiles was smashed into a large hole.
People sitting at home, pee up to the sky?
Don't say, the plane toilet of that year was really a flying in the sky, to the head of the is already very serious, and now you have to in the sky, this wind blows PP cool what kind of process?
Long after the Wright brothers invented the airplane, the plane has no toilet, after all, it flies in the sky for tens of minutes to an hour or two, and it still has to go to the toilet? But later the aircraft changed from military use to civilian use, the number of personnel increased, the flight time was getting longer and longer, and it was impossible to do without a toilet, so the first aircraft equipped with toilets was born.
Caproni Ca.60 Transaereo is the first aircraft equipped with a toilet, the picture above is this legendary aircraft, it is too fierce, people are monoplanes, great biplanes, and it is known as a nine-winged aircraft, unfortunately this aircraft only successfully flew once on Lake Maggiore, the second test flight because the control is too inflexible, the angle of attack when climbing is too large and stalled and crashes.
Supermarine Stranraer
The wind-blown PP cool toilet is on the Supermarine Stranraer (on an amphibious plane), there is a dual-use version, with 6 to 7 passengers, there is a famous "whistling shithouse" (whistling toilet), because when opened the toilet directly with the outside air circulation, the air flow through the exit will produce a whistle, so the pilots gave it various nicknames, such as Flying Meccano Set" and "The Marpole." Bridge ”、“Seymour Seine Net”、“Strainer”、“ Lion's Gate Bridge"。
The chemical toilet on the B-17 is located next to the main entrance door of the 7th
In the Period of World War II, for example, the "Air Fortress" B-17 with a chemical toilet, what does it mean, is a bucket filled with chemicals, a bit like a dry toilet, just put some bleach in the urinal in advance, etc., to eliminate some odor, but it is not very convenient to use, and may even cause feces to "spew out" because of aircraft maneuvering, and the cabin is everywhere.

Some fighters that fly long distances will also be equipped with some "pressure relief tubes" to facilitate pilots to urinate directly outside the aircraft, but the high altitude is often frozen and extremely unfriendly to female pilots.

Toilet of C-54
After World War II, long-distance airliners are basically equipped with toilets, generally according to the standard of a toilet for 50 passengers, the toilet is no longer open to the outside, but there is a storage tank under the toilet, the early is the ordinary toilet, the American inventor James Kemper invented the vacuum toilet in 1976, this toilet is very water-saving, and the toilet wall is not sticky PTFE material, when flushing the toilet, there will be a vacuum pump between the toilet and the storage tank, which will suck the toilet into the storage tank, There is no difference between using it and the home toilet, but there is a funny story about why the toilet button should be placed on the back:
It is said that a flight in the United States in the flight, there is a passenger is relatively large, sitting on the toilet basically put the entire toilet to suppress, and then after the toilet is completed, the hand is pressed in front of the button flushing, the result of the aircraft toilet flush is negative pressure flushing, that is, the toilet high pressure, fecal storage tank low pressure, directly the feces urine "squirted out", the result of this negative pressure will be the giant fat person to firmly suck on the toilet.
The flight attendants and flight attendants tossed and turned for a long time to get him out of the toilet, so from then on, the aircraft toilet flush button was behind, if it was not a very flexible friend, it was difficult to press the toilet flush button without standing up.
However, this happened again in August 2012, according to the People's Daily News, when a big sister was toilet on an airline flight, because she was too flexible, she directly turned around and pressed the button, and as a result, she was firmly sucked on the toilet and tossed for more than an hour to get her out.
So you flexible fat people don't try it, or you will be embarrassed!
When the flight arrives at its destination, in addition to unloading luggage, cleaning, disinfecting and replenishing fuel and water after the passengers get off the plane, while the ground staff inspects the aircraft, there will be a sewage suction truck, which is to suck away the dirt in the storage tank to make room for next use.
There is no toilet on the fighter, what should the pilot do with diarrhea?
Someone on Quora shared a story in which an A10 attack aircraft showed a "brown code" in the flight control center after a long-distance transition flight, and landed first under the "non-jet emergency" and taxied directly to the end of the runway.
Then seeing the engine shut down, the cockpit canopy raised, the gangway open, the pilot (A10 attack aircraft) jumped down with a cardboard box in his arms, and just under the gaze of "God" and the ground crew and the tower, he took off his flight suit, then crouched down, and came with a painful release.
Of course, there are also those who encounter diarrhea during the flight, such as another pilot sharing that an E-2 early warning aircraft is on a mission, and then one of the members has diarrhea, can only solve it by themselves, there is no place to conveniently pull in their own flight bag, and as a result, a certain atmospheric pressure bag in the flight backpack exploded in a low-pressure environment, throwing all the stool out, making the cabin everywhere. As a result, after landing, the ground crew found that everyone was wearing a flying mask, and usually these big masters never liked to wear that thing.
Another case is during the Vietnam War, when an F-105 was supposed to carry out a bombing mission, but asked for "emergency physiological reasons" to land, and after being approved, it was asked to continue the mission, because it was too late, and you probably knew what happened.
Since and urine don't come from the sky, where does blue ice come from?
The above article is a bit long-winded ha, but very interesting things to write can not be stopped, you readers forgive, the following to talk about since the current aircraft toilet has been closed, how can there be a plane toilet ice fell to the ground?
Wastewater lines on aircraft
First of all, let's analyze which area of the aircraft will this blue water appear in? The water in the general sink is clean and colorless, the pantry location at the back of the aircraft is also colorless, the blue liquid can only come from the water of the aircraft flushing toilet, and a biodegradable deodorant sachet, named "Callington Blue Lagoon Water", can be found on the website of the manufacturer of special chemicals in the aviation industry, designed to be used as an aircraft toilet, with a fragrance, suitable for recirculation and vacuum flush toilet systems.
Biodegradable deodorant sachet
The source is found, so how did it leak out? Because of the long aging of use and the high-altitude pressure difference, some leaks occur on some connecting pipelines during some flushing, which is rare but also belongs to the normal category of aircraft pipeline leakage.
When flying at high altitude, due to the relatively low pressure outside the cabin, because of gravity and air flow, these liquids are brought to the outside of the cabin, the low temperature leads to gradual icing, if the amount of liquid is relatively large, the weight of the icing is also very impressive, and in the aircraft into the low altitude or because of the vibration caused by the fall off the formation of blue ice.
From 1979 to 2003, there were 27 recorded cases in the United States of "blue ice" falling to the ground, penetrating the eaves and smashing cars. On average, it looks like more than once a year, and the probability is still relatively low!
Some people say that these blue ice are meteoric ice, but unfortunately not, what is the reason? First of all, meteoric ice theoretically has no fragrance, another problem is that meteoric ice into the atmosphere will go through a high temperature process, the probability has been reduced to water vapor, the probability of falling to the ground is almost zero, and finally the blue and aircraft toilet deodorant sachet is the same, so it can be 100% certain that this is the ice of the aircraft flushing toilet water, as to whether there is before or after flushing the toilet, it needs to be analyzed.
Hope friends who have tasted "Meteorite Ice" will not see this article!
