27. Why are Lights the Dimmed Before Landing?
It may seem like an atmospheric gimmick, but the cabin lights in commercial flights are actually dimmed at night for take-off and landing for a more serious reason. Hint: it has to do with the fact that those are the times when a flight is most prone to problems.

The real reason for the darkened cabin is to allow the eyes to adjust to the lack of light in case of an emergency. The emergency path-lighting and lit signs also become more visible in this situation. This can all help with orientation in each valuable minute of an evacuation or accident.
