A composition about minor mistakes and catastrophes! 700 words

"One step away, it's too late to regret". I think everyone has learned a text, but the specific name is not clear. But the contents will never be forgotten. It is about an astronaut who was killed in a spaceship. Because he changed the international unit, he thought it was a domestic unit. The error was very small, but it led to such a big mistake. This so-called small mistake led to a big mistake. Isn't life like this? A long time ago, I saw such a little joke. A man was very angry and threw a pinball. A teacher came over and accidentally tripped. When he got to school, he was angry with a boy who wrote the wrong question and gave him a good lesson. When the boy went out, he saw a stray dog, so he kicked it hard and kicked it on the secretary of a company. When the secretary goes to work, she always feels sick about what happened today. When the boss asked her to make coffee, she didn't put sour plums, so the boss hated drinking sour ones. So he was angry and had a big fight with his secretary. The secretary was very angry and scolded her husband when she got home. The husband threw a marble on the road to get discouraged.

However, during takeoff, a piece of foam fell off the external fuel tank and hit the wing of Columbia. A big hole with a diameter of 25 cm was knocked out on the wing. Fortunately, the launch was successful. After 17 days of space navigation, the astronauts completed 79 scientific experiments and received instructions from the ground command center to return to Earth on February 65, 438+0. At 8: 44 am that day, the100t spacecraft entered the Earth's atmosphere at a speed of 28,000km per hour. At this time,

Through this accident, I understand some truths: first, sometimes a small mistake may lead to a catastrophe; Second, don't flinch when encountering setbacks and failures, but dare to face them, sum up experiences and lessons, and avoid repeating the same mistakes. I often make some small mistakes, such as missing punctuation in composition, not paying attention to the use of brackets in mathematical calculation and so on. I will pay attention to correcting it in the future.

If I can help you, I hope you can adopt it! ! Thank you ~ ~ ~)
