Airplanes are not as common a means of transport as trains or buses, and travelling on them is an exciting adventure for many people.

There are a few things that may surprise you during your flight. One of them is... the construction of windows.

It turns out that there are tiny holes in them. And this is not a manufacturing defect at all. On the contrary.

Next time you fly, take a close look at the windows. You will certainly notice that their surface is not smooth and uniform in all places. The airplane windows have holes. They are small in size, but can be easily spotted. We assure you that there is nothing to worry about. These holes are necessary and perform an important function during flight.

Thanks to these holes in the window, it is possible to equalise the pressure between the layers of glass. This is necessary for the entire structure to withstand the load of take-off and landing as well as the flight itself. Perhaps surprisingly, it is these inconspicuous holes that enable safe travel.

And speaking of airplane windows, do you know why airplane windows have to be open during takeoff and landing? There are several important reasons. Of course, it's not about taking photos, although that's an added bonus.

Through exposed windows, staff can closely observe what is happening and react quickly if necessary. The view into the interior of the plane also makes it easier to carry out an efficient rescue operation.

Uncovered windows also make it easier for passengers to quickly evacuate. Thanks to the raised blinds, our eyes become accustomed to the conditions outside. We will not be blinded by sudden daylight or surprised by darkness.
