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.

The thought of contracting airborne viruses is something we’d perhaps prefer to ignore while traveling by plane. However, questions about the effectiveness of cabin ventilation systems are definitely something we’ve all wondered about amid the coughs and sneezes in the cramped enclosure.

Despite the rare horror stories, it turns out that plane air is relatively clean. What you are breathing, though, is air from the engine’s compressors (not the engine’s exhaust). What’s known as the “bleed air” system combines recirculated and fresh breathable air. Basically, it’s pretty akin to the air found in an average office.
