Leading aircraft manufacturer Airbus unveiled its vision of flying in 2050, in which passengers will be able to gaze up at sunny or starry skies through a transparent cabin. The new concept cabin features a transparent 360-degree panoramic view with a bionic structure that mimics the efficiency of bird bone.

The cabin's bionic structure will be coated with a bio-polymer membrane, which controls the amount of natural light, humidity and temperature, providing opacity or transparency on command and eliminating the need for windows. This smarter structure will make the aircraft lighter and more fuel-efficient. Future materials may not even be the materials we see and use today. 'Composite' materials will be used – new matter made of a combination of different materials.

The future passenger cabin will be fully ecological. Fully recyclable plant fibers that can be grown to a custom shape will be sourced from responsible and sustainable practices.
