Dear Airlines, please add an AR mode to see outside the plane
Most planes already have Wifi and an onboard computer for media streaming. You just have to add few cameras on the plane and stitch them together to create a 360 view. This can then be streamed to behind the seat display.
Even interesting would be to allow an AR mode streaming to phones. Passengers can point their phones around similar to google skymap and see what's outside with major landmarks annotated.
For more immersion, oculus headsets can be rented at an additional cost. Airlines are already quite commodified with not much differentiation. Features like this could push people to prefer one airline over another.
