Pilot camera
Back in the day, you used to be able to visit the cockpit of an airplane and see what the pilots were doing as they flew the plane. It was the best part of flying and was really exciting to see all the buttons and controls that they were using to operate the plane.
Not to mention the window, where you could literally see what direction the plane was flying in. Sadly, for safety reasons they are all gone, but it doesn’t mean that we can’t use cameras to see what the pilots see instead. During flights in Japan, that is an option for everyone.
