Most Expensive Mistakes in All History

Human error is almost inevitable. Here are some of the most expensive mistakes in history.
#1. Seongsu Bridge Collapse
The Seongsu Bridge is a bridge built by Dong Ah Construction Industrial Company[ over the Han River in Seoul, South Korea. It links the Seongdong and Gangnam districts. The cantilever bridge was completed in 1979 and its total length is 1,160 metres (3,810 ft).
Collapsed bridge in 1994
The original bridge collapsed early on the morning of October 21, 1994, when one of its sections broke off due to failure of the supporting truss, caused by a faulty weld. A total of 32 people died and 17 were injured in the accident. In the aftermath of the event, authorities planned to repair the bridge, but its structural weaknesses made a repair unfeasible and it was eventually dismantled and replaced. The new design was finished on 15 August 1997, and is similar to the original design.
#2. Lotus Riverside Disaster
Building Collapsed In Shanghai(06/27/2009)
At around 5:30am on June 27, an unoccupied building still under construction at LianhuananRoad in the Minhang district of Shanghai city toppled over. One worker was killed. Accordingto information, a 70 meter section of the flood prevention wall in nearby Dianpu River and thatmay have something to do with this building collapse.But the high-resolution photos are really amazing.
Improper construction methods are believed to be the reason buildingcollapse in Shanghai, according to a report from the investigation team. The investigationteam’s report said that workers dug an underground garage on one side of the building whileon the other side earth was heaped up to 10 meters high, which was apparently an error inconstruction
#3. The Baltic Ace
On December 5, 2012, the car carrier Baltic Ace sank in the North Sea with more than 1,400 cars on board after a colliding with a containership near the entrance of the main shipping channel leading to port of Rotterdam, claiming the lives of 11 crew members.
The ship came to rest at a depth of just 35 meters, posing a threat both to the environment and navigation in one of the world’s busiest shipping lanes.
For the salvage, the Dutch Government hired maritime services provider Royal Boskalis Westminster and its partner Mammoet Salvage, who were given the deadline of December 31, 2015 for the complete removal of the wreck and all cars.
The project began in 2014 with the original plan to cut the ship into six large sections and lift them individually to the surface, but inspections revealed that the structures were too weak, forcing salvors to come up with an alternative
#4. Mars Climate Orbiter
The Mars Climate Orbiter (formerly the Mars Surveyor ’98 Orbiter) was a 638-kilogram (1407 lb) robotic space probe launched by NASA on December 11, 1998, to study the Martian climate, Martian atmosphere, and surface changes and to act as the communications relay in the Mars Surveyor ’98 program for Mars Polar Lander. However, on September 23, 1999, communication with the spacecraft was permanently lost as it went into orbital insertion. The spacecraft encountered Mars on a trajectory that brought it too close to the planet, and it was either destroyed in the atmosphere or escaped the planet’s vicinity and entered an orbit around the Sun. An investigation attributed the failure to a measurement mismatch between two software systems: metric units by NASA and US customary units by spacecraft builder Lockheed Martin.
#5. The Vasa
Vasa or Wasa is a Swedish warship built between 1626 and 1628. The ship sank after sailing roughly 1,300 m (1,400 yd) into her maiden voyage on 10 August 1628. She fell into obscurity after most of her valuable bronze cannons were salvaged in the 17th century, until she was located again in the late 1950s in a busy shipping area in Stockholm harbor. The ship was salvaged with a largely intact hull in 1961. She was housed in a temporary museum called Wasavarvet (“The Vasa Shipyard”) until 1988 and then moved permanently to the Vasa Museum in the Royal National City Park in Stockholm. The ship is one of Sweden’s most popular tourist attractions and has been seen by over 35 million visitors since 1961.Since her recovery, Vasa has become a widely recognized symbol of the Swedish Empire.
