[dropcap]E[/dropcap]veryone loves staring out of the window during a flight, the question as to why aeroplanes have circular windows rather than square ones is interesting.
Over the years, aerospace engineering has made huge leaps in aeroplane technology, meaning planes can carry more passengers and go faster. The planes have also changed shape to increase safety including the windows.
In the 1950s, when jetliners were starting to become mainstream, the de Havilland Comet came into fashion. With a pressurized cabin, it was able to go higher and faster than other aircraft.
However, the plane had square windows and in 1953 two planes fell apart in the air, killing 56 people in total.
The reason for the crashes? The windows.
Where there’s a corner, there’s a weak spot. Windows, having four corners, have four potential weak spots, making them likely to crash under stress such as air pressure.
