A company designing a supersonic jet says it will use virtual window displays. The design of the  Spike S-512 Supersonic Jet will remove the needed for the added weight and structural support of windows, without leaving passengers feeling claustrophobic.

The new supersonic jet will feature a revolutionary windowless passenger cabin so no more glaring sun and no more shades to pull down or push up. Instead, the interior walls will be covered with a thin display screens embedded into the wall. Cameras surrounding the entire aircraft will construct breathtaking panoramic views displayed on the cabin screens. Passengers will be able to dim the screens to catch some sleep or change it to one of the many scenic images stored in the system.
