Have you ever noticed that airplane windows are round instead of square? Unlike the square windows of houses and cars, airplane windows have a unique round design for a vital reason related to your safety.
In the 1950s, airplane windows were square, a design that worked well when airplanes flew at lower altitudes and slower speeds. However, as aviation technology advanced, planes began to fly higher and faster, which greatly increased cabin pressure.
This change had tragic consequences. In 1953 and 1954, three plane crashes occurred because the square windows could not handle the increased pressure and caused them to crack. To solve this safety problem, aviation experts redesigned the plane’s windows to be round.
Round windows distribute pressure more evenly, reducing risk of cracks and ensuring more stable flight. Additionally, these windows have a small opening at the bottom, known as a vent, to help equalize the pressure difference between the cabin and the outside air. This opening also prevents moisture build-up and provides passengers with a clear view outside.
Thus, round windows on airplanes are not just a design choice, but a critical safety feature that ensures your journey is safe and comfortable.
