The little TV screen you stare at during flights, particularly long haul ones, is pretty boring. It’s either a movie you’ve already seen, or a digital rendering of the plane on a map/globe.

You could make the flight way more interesting by having a series of camera feeds the passenger can switch between, which show the pilot’s eye view, the straight-down view, the view from the tip of the tail, looking downward and towards the nose, so you can see your plane like in a video game, etc.

The only reservation about this would be the effect it might have on people with a fear of flying. Or if something minor goes wrong that is seen by a passenger and then assumed to be catastrophic and causing panic. But it would be worth the risk, the views would be insane. They could even build in touch-screen functionality or a mechanical button which will send a high-res screenshot to your phone via Bluetooth or something.
