I want to find some serious accidents caused by small negligence, both ancient and modern, Chinese and foreign. If anyone has information, please send it to me.

On August 23, 1967, when Soviet astronaut Komarov piloted the Soyuz 1 spacecraft to return home from its mission, the spacecraft malfunctioned and the parachute could not be opened. All measures taken by the ground command center failed. The spacecraft crashed two hours later, causing heavy losses.

What happened to Soyuz 1 today was because a decimal point was ignored during ground inspection. This tragedy can also be called 'negligence of a decimal point'.

Before the Pearl Harbor incident, the Americans had intercepted the intelligence of Japan’s sneak attack on Pearl Harbor in advance, but due to insufficient attention, Pearl Harbor was attacked.

Japan's Sanyo Electric Co., Ltd. failed to insure its subsidiary semiconductor factory against earthquake insurance in 2004. As a result, an earthquake severely affected the semiconductor factory and prevented it from producing, resulting in a loss of nearly 1 billion yuan. The huge loss of US dollars eventually led to a major adjustment in the board of directors of Japan's Sanyo Electric, which had a great negative impact on the long-term development of the company.

On September 13, "Stock God" Buffett received a call from Bob Diamond, director of Barclays, the third largest bank in the UK. Diamond was planning to buy Lehman Brothers at a bargain price to bring the latter back from the brink of bankruptcy, but he encountered difficulties with the British government, so he hoped that Buffett could provide guarantees to facilitate the smooth progress of the transaction. Buffett, who was eager to get out, said at the time that the trading plan sounded too complicated and asked Diamond to send him the specific trading plan by fax. But Buffett was later surprised to find that he had received nothing.

"Stock God" missed important mobile phone text messages

As the U.S. government refused to provide guarantee for the acquisition of "Lehman Brothers", potential acquirers such as Bank of America and Barclays Bank of the United Kingdom successively withdrew on the 14th. During the acquisition negotiations, "Lehman Brothers" finally collapsed on the 15th.

Ten months have passed. One day, Buffett casually asked his daughter Susan what a small icon on his mobile phone screen represented. As it turned out, he was told that this was the voicemail from Diamond that Buffett had been waiting for that night!

It can be said that it was because Buffett missed a text message that the whole world fell into the shadow of economic crisis
