Have you ever thought about the reason behind the circular shape of the windows in an airplane? Have you also thought about the window shape not being square or rectangular, just like in our cars or in other vehicles? If yes, then here you will get to know why airplane windows are round and not square in shape.
Airplane windows were not made curved initially:
Initially, when planes were introduced in the world they were not as fast as they fly today. Therefore, they used to have square or rectangular shaped windows.
As the aerospace technology advanced with time, airplanes began flying at higher altitudes with higher speeds. As a result of this, in the year 1953, two airplanes fell apart during flight which resulted in 56 causalities. After their investigation was done, it was concluded that the reason for the crash was the rectangle shaped airplane windows.
