How would you like a panoramic view of outside your flight? A company in the U.K. has a concept of doing away with windows in airplanes. The Company is CPI and would use OLED screens lining the entire interior walls, which would show the passengers the view around them.
OLED screens are light weight and also save on fuel because the new airplanes would be able to use thinner materials for the body of the plane. The technology for these planes will be ready in 5 years.
