8 Mistakes and Famous Things We Never Noticed

Mistakes are an inevitable part of life, and they often teach us valuable lessons. This is even more true for masters of their trade, whose errors may remain unnoticed for years and result in calamity. Here are eight famous mistakes that you may not have noticed before.

#8 Square Windows

The first airplane had square windows, which led to an accident that took the lives of 56 people. The corners of the windows took on a high load that became even higher during the flight. You can see the same effect in old buildings, which have deep cracks at the corners of their windows. Soon after the accident, the mistake was corrected. Since then, planes have had windows with rounded edges.

#7 Disney Concert Hall

The structure was built from curved metal frames that protected the hall from the heat and roasted the nearby buildings at the same time. The sun reflecting from the metal surfaces melted the sidings of stores and heated the asphalt up to 140 degrees Fahrenheit (60 degrees Celsius). The problem was later solved by covering the building with a protective layer. Still, many keep wondering jokingly whether it had been an elaborate attack on civilians or just a mistake.

#6 Crazy Horse Memorial

The largest mountain carving in the world is located in the Black Hills of South Dakota. Legend has it that an Indian called Crazy Horse was asked by the conquerors, "So where are your lands now?" The Indian sadly pointed at the horizon and replied, "My lands are where my ancestors are buried." After many years, the state decided to commemorate this by carving a statue of Crazy Horse pointing at the horizon. However, it was found that the pointing gesture in the Indian culture is an obscene one, meaning simply "get out of here."

#5 Aircraft Carriers

Airplanes had difficulty both landing and taking off from the first aircraft carriers. A lack of space made the planes bump into each other, leading to accidents. The engineers solved the issue by turning a part of the runway nine degrees to the side.

#4 Wikipedia

In 2007, several faults were found in the structure of the Encyclopedia that allowed any user to edit any articles. This resulted in vandalism and mistrust of the website. This error was soon corrected, but another one followed suit. The logo of the site is a globe made of puzzle pieces with letters from various alphabets. The mistake was in two symbols because of the wrong spelling. A Japanese hieroglyph and a Hindi character lost their meaning.

#3 Bridgewater Place in Leeds

In 2008, this building was nominated for the ugliest construction in Europe. Because of an engineering error, the wind around it is so strong that it throws people off their feet. When the wind overturned several cars in a parking lot, the traffic near the place was restricted.

#2 The White House

An error was noticed on the White House emblem after it was printed. One window arch looked different from the real one. It was quickly corrected, but other errors followed in the process. Several arches were different now, and second-floor windows had more sections than in reality. This emblem was not amended, and it is like this even today.

#1 Mona Lisa

Leonardo da Vinci loved riddles and secrets, so it's hard to say whether the following are his mistakes or actual intentions. The very name of the famous painting is thought to be a mistake. In Italian, "Mona" means "milady." Leonarda whoever wrote this word with only one "n." X-ray analysis revealed that the painting has three layers. The artist probably repainted it, and many believe he forgot to add eyebrows. And if you look at the lady's right hand, you'll see a strange bump on the wrist. Some think Leonardo da Vinci may have made an anatomical mistake.
