These are silly mistakes that can be avoided if a little more careful calculation.
14. Shanghai apartment complex collapsed

Lotus Riverside apartment complex in Shanghai consists of 11 13-storey buildings. Things have nothing to say until one morning, a building of which it suddenly collapsed. Fortunately, when dumped, this building does not overlap with neighboring buildings and causes a domino effect. The reason for the incident is that the investor does not comply with construction standards and the construction works are constructed with poor quality.
13. Missed the 150-year-old guitar during filming

The guitar that Jennifer Jason Leigh played in Quentin Tarantino's The hateful Eight is actually a super rare instrument. It was created 150 years ago and it was borrowed from the Guitar Martin Museum by a film crew. In one scene, this six-second century-old guitar should be replaced by another. But it seems that actor Kurt Russel was not informed about that and accidentally smashed this artifact into pieces.
12. Buying wrong 2,000 electric trains that do not fit the rail size.

In 2014, the railway company SNCF decided to modernize its transportation network and ordered 2,000 new trains with a total value of up to 15 billion Euros. Unfortunately, the data on the track they received belongs to the design stations in the past 30 years. Many of them are old and a bit narrower than the requirements of new ships. As a result, the company had to spend an additional 50 million Euro to widen the track.
11. Print wrong one glass, go immediately 225 million USD

Japan's securities company Mizuho Securities wants to sell a stock for 610 610,000 (about US $ 5,000) on the Tokyo Stock Exchange. However, a stock broker, not sure if he was sleep deprived, made a "small" mistake when entering data. He entered an order to sell 610,000 shares for only 1 yen per share! Although the company later corrected it, the trading platform handled the code, which made them sadly accept the loss of $ 225 million.
10. Design errors, submarines cannot float out of the water because they are too heavy.

The Spanish government has invested up to £ 1.75 billion to build a new submarine called Isaac Peral. However, during construction, it was discovered that submarines were too heavy and there was a risk of being unable to float out of the water once they had dived. It turned out that someone had mistakenly calculated a few parameters right from the design stage. The solution is to extend the hull to distribute the weight more appropriately.
9. The deal sells Alaska between Russia and the US

At the end of the 19th century, Alexander II of Russia saw Alaska as a land of snow and snow. So in March 1867, Russia decided to sell off this vast territory to the US for only 7.2 million USD. Considering the exchange rate between the Ruble and the Dollar at that time was almost equal, the Russian side answered a little from the deal, in exchange for losing all the natural resources worth billions of dollars.
8. Millennium, The bridge dancing.

Millennium Bridge, connecting the banks of the River Thames in London, was inaugurated in 2000 and closed almost immediately afterwards. The reason is that if there are too many people going to the bridge, it will shake violently. The initial bridge construction cost was £ 18.2 million. But to use safety bridges, another £ 5 million has been spent to rebuild and add structures to stabilize motion.
7. NASA spacecraft lost

The Mars Climate Orbiter was developed by NASA to study the climate on Mars. However, because of an unbelievable mistake, entering the atmosphere, the ship lost contact with the ground. To transmit coordinates, a NASA crew used Imperial units (feet and yards), while another crew used Metric. As a result, the ships were too low in Mars to burn to ash.
6. The sale of Apple stock in 1976

Ronald Wayne is one of Apple's founders. He created the company's first logo and wrote a manual for the Apple I. computer. In 1976, he decided to sell a 10% stake for $ 800. Mainly because he owns some assets that can be withdrawn if the company goes bankrupt. It was a hasty decision: if he kept those shares, he might have become a billionaire at this time, when their value now increased to 80 billion dollars.
5. High-rise buildings make cars melt

With a pan-like design, plus a glass surface, the Walkie-Talkie building in London unknowingly becomes a giant mirror. The reflected light from the building was so bright that it melted the cars parked nearby. Some people even fry eggs thanks to this building. To prevent disaster, people had to attach sun protection shields to the building.
4. The lake is leaking

In 1980, because of oil drilling, a lake with more than 13 billion liters of water was leaked. In the process of drilling wells, it was mistakenly calculated that the drill lost the dome of a pit mine below Lake Peigneur (USA). Gradually, salt and water mix and erode the small borehole into a huge hole. This hole led to the formation of a whirlpool that attracted both the drilling rig and 11 barges, a tugboat, several trucks, and even a small island in the middle of the lake. Unexpected luck is that no one is hurt.
3. Throw bitcoin to the landfill

In 2009, bitcoin has just appeared, so digging this currency is quite easy. The Englishman, James Howell, collected 7,500 dongs of coins, at which point it was almost worthless. By 2013, the value of this bitcoin has increased to $ 7.5 million. But ironically, before realizing his luck, this guy threw away the bitcoin-containing hard drive to the landfill!
2. Vasa - The sinking ship

Vasa, the ship was built on the order of the king to lead the Swedish navy fleet in the 17th century. But this "super product" could not even leave Stockholm Bay and sank as soon as it left the dock. ship. Because of a design error, the ship became extremely unstable. Only a gust of wind blew over, it was capsized and quickly sank to the bottom of the life before the dismayed gazes of thousands of witnesses.
1. The bridge section collapsed on the Korean river

The bridge over the Han River in Seoul became famous after it suddenly lost a beat in the 1994 rush hour. The center of the bridge could not withstand the load and fell into the river, dragging many cars and cars. Small loads, and a bus full of people. The cause of the bridge collapse is because the steel structure supported by the bridge is too sketchy.
