If you have traveled at least once with the plane, you may have noticed that there is a small hole at the bottom of each window. What is her role?

Colombia, the United States, and México. When they arrived at Perú, the airplane windows revealed a crowd of more than 20,000 people spread across the landing



It is not the fault of a manufacturing defect, nor the age of the aircraft, because that must be all the windows in the plane. You do not have to worry if you notice these holes, but only if you do not notice them.

They have a very important role in keeping the cabin pressure at a normal level during the flight. In the event of a depression, only the outside window will break, not the interior window, so that the lives of the passengers will not be endangered, writes Daily Mail.

Each window in the plane consists of three layers: the outer, the middle and the inner window. The inner layer is made of a combination of glass and acrylic to be as durable as possible.

The small hole that you can see is made in the middle window to maintain a balance of pressure between the inner and the outer glass.

If the outside window is destroyed during an incident, the interior will be strong enough to maintain normal pressure and the pilot will have enough time to lower the plane at a lower altitude or even land.

Also, airplane windows have an oval shape to provide better visibility to passengers. In addition, the corners of a square or rectangular glass would concentrate the pressure in these areas and in time the windows would crack.

What is the dirtiest place on an airplane?

A recent study published by Travelmath shows that the toilet is actually the most hygienic place out of a plane. Passengers must take account of this new information, not get sick during the trip.

Researchers took samples of bacteria in several places in four aircraft and five airports, and then analyzed the results to determine which are the dirtiest places. Thus, the toilet flush button that contains only 265 CFU (colony forming units of bacteria) on 2.5 cm square, writes The Independent. Surprisingly, the dirtiest place of the aircraft is on the seatback folding table, which has eight times as many bacteria as a toilet: 2,155 CFU per 2.5 cm square. Here is the explanation: the toilets are among the cleanest places in the plane, that are washed and disinfected after each flight. Instead, these tables are completely neglected between flights. Button Air Conditioning overhead passenger seat belt and contain about the same number of bacteria as toilet flushing button, the study shows.

Thought the weirdo in the window seat was your biggest worry? Think again. The CBS news station in Dallas checked the cleanliness of airplanes on two recent flights. The CBS 11 investigation revealed all sorts of ick.

Researchers is every traveler's advice to use special hand washing gels when in flight and not on the table eating away. These tables are usually only cleaned at the end of the day, not between flights as cleaned the toilet. The crew on board does not have time to clean up all the objects in the plane, such as the passenger safe and hygienic. The study also demonstrated that airports are the dirtiest places The nipples drinking water exactly which button should be pressed to gush water. These buttons have 1,240 CFU per 2.5 cm square. Instead, the toilet seat has only 172 CFU per 2.5 square cm, according to a study conducted by the National Science Foundation in the United States.
