Why are airplane windows round?

It turns out that aircraft window design is more about safety than aesthetics.

If you ask a young child to draw an airplane, they are more likely to draw an oval window, but airplanes have not always looked like this.

The de Havilland Comet, an early commercial aircraft design, had square windows. But within just five years of their introduction, three planes had a series of tragic crashes.

After the third crash in 1954, investigations determined that all three crashes were caused by broken window frames, a result of their square design. It was found that square windows cope very poorly with the pressure that comes from flying at high altitudes.

Meanwhile, high altitude is a necessary element of soaring, which means less fuel used. This is ideal for airlines because it saves them money and reduces the impact of flying on the environment. There is also less turbulence at higher altitudes, which makes for a more comfortable flight.

What was the solution? Replacing square windows with oval ones. This helps to evenly distribute the pressure exerted on the window and thus reduces the possibility of cracking.

"The narrower part of the oval was designed to ensure that no pressure is generated in the material," explained Dai Whittingham, chief executive of Britain's Aviation Safety Committee.

In addition to the element of increased security, there are still some more superficial benefits.

"Oval windows are preferred because they can have a larger viewing area," Whittingham said.
