"To answer your question, we first need to figure out the odor structure of farts!"
Bei Haiyang was serious. Only Wang Dapao understood it best. He quickly destroyed his food before he could spit out the fragrance. If it was too late, he might not have a chance. He didn't want to fly back hungry.
It's a pity that the flight attendants are completely unaware of the dangers involved.
“99% of a fart is odorless gases: nitrogen, hydrogen, carbon dioxide, methane, and oxygen.
How to convert odor-causing substances into aromatics? You can witness the birth of a fragrant fart!"
Meng Zhiqiu reluctantly put down the food in her hand. She is a person with slight mysophobia, and she doesn't want to eat it now. Is it really appropriate to analyze the structure of farts in such an occasion?
The silent first officer was still complaining, "According to this problem-solving idea, the first step is to eliminate the odorous compounds, hydrogen sulfide, indole, and skatole, which are the three major culprits of smelly farts!
They are produced by eating sulfur fiber foods, such as garlic, leeks, radishes, celery...
You all studied chemistry in junior high school, right?"
Lin Shanshan silently pushed away the vegetable salad in her hand, and there were a few slices of crisp and green celery...
The young man scratched his head and said, "It sounds familiar, but it's just not quite..."
Bei Haiyang has a rich reserve of knowledge. “When these foods fall into the human intestine, they will be welcomed by various bacterial flora!
Fiber food is decomposed into hydrogen, methane, and oxygen under the reception of methanogens.
However, 2/3 of people lack the archaea called methanogens in their intestines, so they lose their special ability to ignite farts and produce hydrogen sulfide that smells like rotten eggs.
Have you ever smelled the smell of rotten eggs? It’s the kind that has been left in the refrigerator for more than a month and forgotten..."
You Xiaofei put down the knife and fork in his hand in embarrassment. There was still half a tea egg left on the fork...
The boy was too young to notice this at all, "I've smelled it! But mine... isn't that smelly!"
Bei Haiyang earnestly taught, "Sulfur-containing foods are taken away by Clostridium perfringens, causing a putrefactive reaction to form a stink bomb... Therefore, eating less sulfur-containing foods is a prerequisite for farting!"
I said this, do you understand?"
The young man's face was full of admiration. He didn't know that a pilot actually needed to understand so many levels of knowledge. It was indeed a unique profession.
"Uncle, your explanation is really good. I understand."
Bei Haiyang didn’t mean to end it yet, “After talking about hydrogen sulfide, let’s now deal with indole and skatole!
Indole and skatole have two faces in private. When the concentration is high, it smells like shit, and when the concentration is low, it smells fragrant...
Indole emits the smell of animal feces at high concentrations, and has an aroma similar to jasmine at low concentrations. After indole is diluted, it is used as daily flavor and food flavor. The dosage is about 0.6ppm, which means the dilution concentration is 6 parts per 10 million...
"
Sister Yao felt uncomfortable all over. She liked perfume very much, especially the jasmine scent, like the one she was wearing now... Compared to the other three flight attendants, her perfume usage was significantly higher.
There are also reasons for personality, and there are also reasons for age... But if you spray too much, it smells like shit?
The young man's eyes widened. He had completely forgotten the embarrassment of farting. "It's amazing that there is such a thing. Is it shit because it smells so good?"
Bei Haiyang is extremely patient. “When the concentration of skatole is high, it smells salty and nauseating, but when it is at low concentration, it smells like a big civet cat or ripe fruit. It is widely used in food flavors, and the dosage is 0.8ppm…”
The young man was immersed in the ocean of knowledge, and the clear baritone voice of the captain's uncle came to his ears, which attracted him firmly like a magnet.
"According to the material properties of indole and skatole, if you fart in a hot water pool of about 2,000 tons, well, it is the size of a standard swimming pool, the fart will emit the aroma of a civet lying in the jasmine bushes eating fruits!
Isn’t it satisfying? Isn’t God magical?”
Li Zihan stood up. He didn't care if someone said disgusting things during the meal. These tricks were child's play in the army! But he especially liked swimming. Now that he remembered that there was always a faint aroma in the swimming pool he often went to, he let
He wanted to cry but had no tears.
He originally thought this was the swimming pool taking care of the guests' welfare, but now it seems...
The young man suddenly came back to his senses and said apologetically: "Uncle, all your colleagues are gone! Are you ready to take off? Thank you uncle for your explanation. You are the most knowledgeable captain I have ever seen!"
Bei Haiyang stood up. Of course he knew why these colleagues left, and it didn't matter.
Patting the boy on the shoulder, "So, it's just a fart! You don't need to apologize to anyone for this!"
………………
Boarding the plane again, Wang Dapao was on business.
"This time I take off and you land!"
Bei Haiyang nodded in agreement, this is also a rule; Wang Dapao has the responsibility to teach newcomers, so proper arrangements must be made during takeoff and landing. Newcomers must be involved in every important flight operation. This is also one of the captain's missions.
He didn't say much. He was already powerless to change this usually taciturn guy. Young people have such a personality and they can't be rigid. It's another thing to end up suffering a loss for this in life.
You have to walk your own path! I hope he can suffer a loss earlier, so that there is still time to change, and don't be like him who has achieved nothing even after he was 60 years old!
It is still a step-by-step operation process, the only difference is that it has changed the direction and the landing site.
At 4:15 in the afternoon, Flight 4607 took off from Syracuse on time, and under the control of Wang Dapao, it sank into the already darkening sky.
In the cabin, after the initial busyness, several flight attendants gathered together. Sister Yao was very energetic.
"I see that everyone didn't have much to eat at noon. How about a meal at night? I'll treat you!"
You Xiaofei clapped his hands, "Okay, okay! But it's still AA, right? Sister Yao, you've already invited me once this month, why are you so embarrassed to invite me?"
As flight attendants, their income levels are not at the same level, so it is difficult for several flight attendants to be as generous as Sister Yao, and unlike Sister Yao, who is a native of Donghai, the income of a flight attendant has to cope with the high rent and high rent in Donghai.
With countless expenses involved, life is always tight.
Not many young people today are careful about their finances. The collision of civilizations hangs on the top of their heads. Of course, they must enjoy themselves to the fullest to make their visit to this world worthwhile.
Several people quickly agreed that although they often stumbled over small things, overall the relationship was pretty good, and dinner gatherings were frequent.
Meng Zhiqiu hesitated, "So, do the captains call them? Or..."
Lin Shanshan said bluntly, "Shout! Just call me Captain Wang! Let's forget about that Bei Haiyang. Don't say a few words while eating. Should we eat or not? I have never seen such a person. No wonder Er
I'm sixteen or seventeen and I don't even have a girlfriend! I deserve to be a bachelor for the rest of my life!"
