You don’t need a window for these views. Paris-based design company Technicon Design recently won an award for their IXION Windowless Jet Concept. The idea is to provide a 360-degree view using cameras mounted on the plane’s exterior to capture the scenery and then project that on high-res screen on the interior cabin walls and ceiling.

And actually any scene could be displayed on the interior. Let’s say the view is mostly clouds or ocean. How about displaying a rainforest? A flight through the Grand Canyon? A trip to the Moon?

Solar panels on the exterior would help power the displays.

Removing windows has its advantages, too. It reduces the materials and cost needed as well as reducing the weight of the plane. Not having windows allows for a greater flexibility of the interior design of the aircraft, too.

“The ethos of the project is simple, to challenge current thinking, and propose something a little different, but not just a fantasy. It has to be credible and relevant, yet provoke discussion,” design director Gareth Davies said in a press release.

What a nice concept! The view is even better than the views from the window.

@kelvin you're right
