A cabin window consists of three panes: 1) an outer pane flush with the outside fuselage, 2) an inner pane which has a little hole in it, 3) a thinner, non-structural plastic pane called a scratch pane. Figure 1: A typical commercial airplane passenger window.

Why is the airplane an important invention?

The airplane is without a doubt the most influential invention of the 20th century, simply because it shrunk the world. It has connected nations that would have never been connected otherwise, and shown us a new, unseen and spectacular perspective of our earth.

Why are the aircraft windows round or oval in shape?

Sharp corners naturally concentrate more stress, which further gets weakened by the immense air pressure. Curved or round windows distribute the stress of the outside pressure of air, and thus are stronger and prone to deformation because of the pressure.

How are aircraft windows made?

The windows on a modern airliner are actually made up of multiple layers, usually three, of acrylic with a plastic inner cover. The three layers are gapped and vented. This is to allow for pressure equalization and to prevent the windows from fogging.

Why do airplanes have windows?

The design of aircraft windows falls into the school of hard knocks category. In the early days of aviation when passengers were first being carried, windows were found to be required as people would tend to become quite claustrophobic in a windowless tube.

Do round windows look better on a plane?

Yes, it does look sleeker perhaps and gives a streamlined impression. To be honest as far as streamlining goes it matters not whether the windows are square, round or some other shape, as they are flush with the fuselage metal and the air goes past them just as happily. So, is there another reason for rounded windows?

Are aircraft cabin windows made of glass?

The main thing to know is that aircraft cabin windows are not made of glass, but with something called “stretched acrylic”. It’s a lightweight material manufactured by a few global suppliers for the various aircraft flying today.

What did the first airliner windows look like?

The early airliner windows resembled those you might find on a bus. They were usually rectangular in shape and came in various sizes depending on who’s aircraft you were in. Passengers would have the opportunity to enjoy the view and assure themselves that they were indeed flying right side up.
