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.
雖然不是每個人都會在飛行中凝視窗外的時候思索一個問題:為什么舷窗是圓形的而不是方形的。但這個問題很有趣。
Over the years, aerospace1 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 mainstream2, 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, killing3 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.
