The design of the plane window is crucial.
HAVE you ever wondered why aeroplane windows are round?
It may sound like a minute detail — but the shape of a plane’s windows is actually really important.
In the past, square windows were all the rage and many early plane designs featured them.
However, by the time the 1950s rolled around, the commercial jetliner rose to fame — and this is when problems began to surface, The Sun reports.
The new planes were capable of flying at greater speeds and at higher altitudes than those of the past, but two of them soon fell apart, disintegrating midair — all because of square shaped windows.
This may sound bizarre, but it all comes down to the sharp corners on a square.
The corners are natural weak spots, more likely to be stressed and weakened by air pressure changes and as such are a recipe for disaster when it comes to air travel.
Curved windowpanes, however, have no focal point and distribute stress evenly — reducing the possibility of cracks or breaks.
Yep, that’s a view.
Circular windows are also stronger and resist deformation, meaning they fare far better when it comes to extreme differences in air pressure between the inside and outside of the plane.
