And curiosity led me to inquire about the only air crash in Wenzhou, which was around 16:30 on February 24, 1999. The plane crash killed more than 60 passengers and the crew, and all of them were killed because the maintenance engineer installed a self-locking nut that did not comply with the regulations, which caused the nut to fall off during the flight and could not control the crash.

At that moment, I could understand a little bit that it might just be a small problem for one person. It has resulted in the death of more than 60 passengers, so the emphasis in so many books may be to talk about the dangers caused by the insecurity of a small nut.

The first exam half a month later was to write fill-in-the-blank questions on a computer in the computer room of a complex building outside the airport.

The rules are similar to those of a driver's license, and you can pass the test with a score of 95 or more.

Roughly speaking, you will be able to enter the airport after that, but you will need to wait for the next time you take the test.

I was the first to arrive at that time, and then a lot of middle-aged people and aunts came one after another.

I looked very young in it just after graduating, and next to me was an old aunt.

I tried to ask, "Auntie?" Are you also coming to the airport? ”

My aunt smiled and said to me, "Young man, I'm here to sweep the floor." ”

"It's not an aunt, sweeping the floor has to take an exam? Do you understand all the hard books you read? I said puzzled.

"What book?" Aunt said puzzled.

"Those safety rules?" I said.

The aunt took out a piece of paper from her pocket and spread it out.

The top is densely packed with multiple-choice questions, with more than 100 positive and negative questions.

The aunt shook the paper and said, "The young man said this, right?" I can't memorize it when I'm old. This is what the airport prepared for me, and I am a sweeper outside. If you can't see the plane, you won't do anything to the plane. ”

I was a little embarrassed and looked around.

There are really a lot of people around who have cheating notes, and most of them are older.

Helplessly, the exam began, and I looked at the aunt next to me while answering the questions, and looked down at the paper in my hand.

The examiner passed by and glanced at the aunt, but reminded on the side: "After reading it, remember to take it away and don't put it on the table." ”

Seeing that the examiner acquiesced to the aunt's direct copying of the answers, I was also a little helpless.

Ten minutes later, an uncle in the two rows of seats in front of him sighed and said, "Eighty-nine, this week has come in vain again." ”

I looked at his computer interface, and it turned out that pressing OK would directly count the results.

When I finished the fifty questions, I panicked when I saw the button to confirm the submission.

Because I could see that many people around me were disappointed after pressing OK, the aunt next to me suddenly smiled and said, "One hundred points, it's over." ”

I don't know why I think it's a little ironic, but thinking that people just apply for sweeping jobs really don't need to be so difficult for her.

My aunt looked at me and whispered, "Young man, I'm over." Look at you have been stunned here for a long time, do you not know how to do it? You just called me Auntie, not like those rude old women who call me old women. I'll leave you this paper, I'll go first. ”

My aunt pushed the paper to my computer desk and got up to leave.

I reached for the paper, looking a little overwhelmed.

I glanced at the invigilator teacher, who was watching the TV series on his mobile phone on stage at the moment.

I can be sure that the invigilator doesn't care whether the person copying the exam or not, and I don't dare to press the sure and I want to check whether my answer is correct.
