?Why are airplane windows round
At the beginning of the fifties, the De Havilland Comet was introduced as the first jet passenger aircraft produced in the world. This event was a miracle at the time... but unfortunately, a year later, the plane fell in pieces... but the matter did not stop there. And even within several months, two planes also crashed... so the engineers conducted a comprehensive and careful examination of all parts of the planes, starting with the engines and large parts, all the way to the screws... Finally, they found the problem:
! The windows were square! Yes, do not be surprised, as that was the mistake, as the windows are square
He explained the matter: The pressure appears stronger around the corners of the square windows, and of course the pressure naturally increases during flight... That is why it was decided to make the windows round, and because of this decision, flights have become safer until now.
The goal of this step was to save money, because flying at high altitudes means that the air density will become less, and thus air resistance will become less, which also means less fuel consumption and saving money.
