While not everyone will have pondered the subject while staring out of the window during a flight, the question as to why aeroplanes have circular windows rather than square ones is interesting.
 
虽然不是每个人都会在飞行中凝视窗外的时候思索一个问题:为什么舷窗是圆形的而不是方形的。但这个问题很有趣。
 
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[1] 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.
 
By curving the window, the stress that would eventually crack the window corner is distributed and the likelihood of it breaking is reduced.
