Airplane Windows - If you flew before the 1950s and had a window seat, you would look out of airplane windows that were completely different in shape than they are today. So why has it changed?
If you love the window seat or prefer to sit so far away and forget you're flying, you'll definitely notice that all the windows on the plane are round - which is a pretty cool fact about planes. It's something you've probably never wondered about because that's exactly what it is - just like you've probably never wondered what happens when you flush a plane or some airplane sound.

But is there a reason airplane windows are round? Does this shape really help the plane stand up straight, or are the curved edges just more aesthetically pleasing? After answering this airplane question, look for answers to other airplane questions, such as why "airplane" is also spelled "airplane", real aircraft, at what altitude, and what happens to rear-facing airplane seats.
Have You Ever Wondered What The Small Holes In Airplane Windows Are Used For?
Always round - they used to be square. They were square until the 1950s, at a time when planes flew slower and lower. So why do flat features completely change shape?
Willis Orlando, product operations specialist for Scott's Cheap Flights, says the circle, while soothing to the eye, serves more than just an aesthetic purpose. “The rounded corners are designed to help evenly distribute the pressure applied to the window, reducing the chance of cracking due to changes in air pressure,” explains Orlando. By the way, that's why it's so cold on the plane.
As flying became more common, airlines began flying at higher altitudes to cut costs (where there was less drag, limiting unnecessary fuel usage). The planes themselves are also subject to increasing pressure, increasing the pressure difference between the inside and outside of the plane and causing more stress.
That's when square windows start to become dangerous. In 1953 and 1954, three separate planes - all De Havilland Comets, the first jet airliners - disintegrated in mid-air due to concentrated stress caused by the sharp edges of the windows. Analysis of crashes and similar injuries to passengers demonstrated that "metal fatigue failure" - which originated in the corners of the windows - caused the plane to crash. This resulted in the oval design you see today, as voltage can flow more evenly around the round window instead of pooling in the corners of the square window. With this new and improved shape, tension can flow and we can fly safely.
