CPI, based in north east England, believes the idea will quickly take off as planes without windows are much lighter than planes with them, and as airlines battle to save money and fuel, cost is one of their main considerations. A lighter plane will burn less fuel and will produce less CO2 emissions, which will also be better for the environment.
The entire inner surface of the fuselage would be covered with high definition, flexible displays, which would be used to conceal cabin utilities. Cameras could be mounted on the outside of the fuselage, which could then potentially give an uninterrupted display of the exterior.
But the inner surfaces could also simply be used for lighting, which could be changed to mimic sunrise and sunset on long haul journeys.
A French design agency also released its first drawings of a windowless passenger jet in August: the Ixion Windowless Jet. Although there are no firm plans yet to build the plane, with a growing number of companies committing their ideas to the drawing board, the development of the windowless plane may just be a matter of time.
Spike Aerospace from the US is also aiming to re-launch supersonic flights between New York and London (the last commercial flight by Concorde was in October 2003) in 2018, and expects its aircraft to be built without windows.
