Whenever we board a plane, cross the clouds, and enjoy the convenience and comfort of high-altitude travel, few people will think about a seemingly everyday but rather mysterious question - what is the toilet excrement on the plane?Imagine that if you go to the toilet at an altitude of 10,000 meters, will those wastes really "parachute" directly to the ground, or suspended in the air, becoming alien objects?
The mysterious journey of the airplane toilet: an unexpected "gift" from high in the sky to the ground
Imagine you're sitting on a speeding green train, enjoying an affordable trip, when suddenly a cool breeze blows through the toilet and makes you shiver. This is because the toilets on the train are underneath the tracks, and your "waste" will be blown by the wind and fall directly onto the tracks. This is how the early train toilets were "straight down".
But what if I said that the same was true of the early airplane toilets?
Yes, you heard it right. Early airplane toilet designs weren't as advanced as we think they are now. Just like the green train, when the plane is flying at high altitude, the excrement in the toilet is also discharged directly into the air. Of course, due to the altitude and speed at which the aircraft flies, this excrement is quickly frozen and decomposed in the air, eventually turning into imperceptible ice crystals.
However, just like there are always unexpected "surprises" in life, if you are "lucky" enough, there is still a chance that you will be hit by these "gifts" that fall from the sky on the ground. Although the probability of this happening is extremely low, imagine that you are enjoying the sun outdoors and suddenly an unknown object falls from the sky, and that feeling must be "exciting".
With the advancement of aviation technology and the increase in environmental awareness, the toilet system of modern aircraft has been comprehensively improved. Nowadays, excrement from airplanes is stored and disposed of by professional cleaning staff after the plane has landed. This not only protects the environment, but also avoids unnecessary "surprises" for ground personnel.
Still, whenever I think of the early airplane toilet design, I can't help but sigh: it was really an era of "the sky is high for the birds to fly, and the sea is wide for the fish to leap"!
Misfortune from above: the bizarre encounters of British men and the hidden corners of the aviation industry
On a sunny afternoon, the unlucky Mr. in England is enjoying a moment of tranquility in his garden leisurely admiring the flowers. However, this calm was suddenly shattered by a lump of unknown liquid falling from the sky, and the disgusting stench instantly spread, staining his otherwise good old days into nightmares. Mr. Unlucky looked up in shock and saw a plane disappearing in the distant sky, and it dawned on him that he had been hit by the excrement on the plane
Mr. Unlucky's family lives near Heathrow Airport, and on weekdays, the roar of airplanes is just the background sound of life for him. This time, however, he became a victim of the "development of the aviation industry" in such an unbearable way.
After the purge, he was determined to find out the truth, and by looking up the flight records, he quickly locked down the flight in question. But when Mr. Unlucky complained to the airline, he was met with strong denials from the other party. In desperation, he had no choice but to take the matter to the city councilors, hoping to get a fair explanation. The city councillor took the matter very seriously and immediately launched an investigation. The results showed that the aircraft involved was using a chemical toilet, and due to improper operation, the toilet wastewater was not closed tightly, which caused the fecal water to leak and freeze in the air and hit the ground. Shockingly, British Airways statistics show that 25 out of 2.1 million domestic flights a year have similar incidents!
This incident not only caused Mr. Bad Luck to suffer unjustifiable disasters, but also revealed a little-known hidden corner of the aviation industry. Behind the pursuit of efficient and convenient modern air travel, there is such an unbearable side. For airlines, how to ensure the basic rights and safety of passengers is obviously an urgent problem to be solved.
And for every one of us ordinary people, the experience of Mr. Bad Luck also makes us wonder: should we also be vigilant enough about the potential risks brought by technology while enjoying the convenience brought by technology?The Awkwardness of Flying: "Justice from Heaven" on Airplanes and the Evolution of Toilet Systems
Imagine you're enjoying the tranquility of flying high and suddenly a shrill alarm goes off, followed by the sound of a toilet seat banging on an airplane. This is not the plot of a horror movie, but a real scene in flight before the middle of the last century - at that time, the "bombs" after the pilot went to the toilet were no joke, they were literally thrown directly into the air and smashed to the ground by gravity.
It may sound like an old historical anecdote, but it was really the daily routine of a World War II pilot. Those warriors in the sky, while carrying out their mission, also had to face an embarrassing truth: their toilet facilities were rudimentary, and the way they disposed of excrement was primitive. Of course, this also brings a lot of trouble and danger to the people on the ground.
Time jumped to the 60s of the last century, and civil aviation aircraft began to gradually enter people's lives. With the popularity of flying, the facilities on the aircraft are also more user-friendly. The emergence of chemical toilets is supposed to solve this problem, but the headache is that the phenomenon of "justice from heaven" still occurs from time to time. Passengers may be able to enjoy the flight from the comfort of their seats, but the people on board will have to be ready to "pick up".
So, how exactly are these embarrassing "bombs" handled?With the advancement of technology and the pursuit of comfortable flight, the toilet system on board the aircraft has undergone several important innovations. Eventually, after years of R&D and improvement, a perfect toilet system was finally created. This system is not only able to effectively dispose of the excrement on the plane, but also ensures that they do not become "uninvited guests" to disturb people on the ground.
Nowadays, when we fly through the clouds, we may rarely think of this vital system hidden in the corners of the cabin.
It works quietly to ensure that our flight experience is more comfortable and safer. But looking back in history, we will find that behind every technological advancement, there is an interesting and little-known story. So, the next time you hear a flight attendant on a plane alerting you that "the restroom is closing," think about the long journey this tiny toilet system has been through. It is not only a product of technological progress, but also a testimony to the relentless pursuit of comfort and dignity by human beings.
The magic of "cleansing" in the sky: unraveling the mysteries of the airplane toilet system
The toilet system on the plane is like a "cleaning magician" in the sky, silently disposing of all kinds of "unclean things" to keep the cabin fresh at all times. The magician's "magic wand" consists of two parts: one is a container dedicated to storing liquid garbage, such as sewage and fecesThe other part is a mysterious device that disposes of this garbage.
Interestingly, this magician is also proficient in the magic of "wet and dry separation". With this technology, sewage and feces on the aircraft are effectively sequestered and do not produce unpleasant odors even when the aircraft is turbulent. At the same time, the ventilation system on the aircraft works continuously, not only circulating fresh air, but also quietly sending sewage to specific locations for treatment. That's why we always find toilets at the rear of the aircraft, while lavatories are located at the front of the cabin.
Before the plane takes off, the crew will perform a "emptying magic" to pour the excrement from the plane into a large bucket. When the aircraft takes off, the waste is dumped into the sewer and transported to the airport's designated location for more complex treatment, including condensation nucleus separation, collection and final disposal.
So, how did this "cleansing magician" do all this?In fact, behind it is a series of complex engineering and technological support. From material selection to system design, every step has been carefully developed and tested to ensure the efficiency and reliability of the aircraft toilet system.
Nowadays, when we fly through the clouds, we may rarely think of this vital system hidden in the corners of the cabin. But it is precisely its existence that allows us to enjoy a comfortable and clean environment in the sky. The next time you walk into the airplane toilet, you might as well say thank you to this "cleaning magician" who has worked silently
