15 Hidden Airplane Features You Never Knew Existed

10. Supplemental oxygen

Some planes stock extra oxygen tanks for passengers who need help breathing in addition to the drop-down oxygen masks that come standard.

11. Cockpit camera

Cockpit cameras are meant to supplement the information found on the airplane’s famous black box, but pilots have been fighting against their installation, citing privacy laws. Some airplanes do have them.

Next: You can never have enough oxygen.

13. Fire extinguisher

Most fire extinguishers on airplanes use a liquefied gas that puts out the fire using a vapor. The engines of planes also have built-in fire extinguishers that can be activated from the cockpit and will stop the fire from spreading. The US Federal Aviation Administration stipulates that the materials used to construct the passenger cabin must also be self-extinguishing.

Next: Pilots fought against using these.

14. Axe

Airplanes used to stock axes in case of a crash so that the crew could break through panels to fight an electrical fire. You might still see them today, but most airlines have replaced axes with crowbars as an anti-terrorism measure.

Next: In case of a fire, grab this.

15. Surveillance cameras

JetBlue was the first airline to install surveillance cameras after the tragic events of September 11, 2001. Some of the cameras are visible and some are hidden — but no matter where they are, JetBlue maintains a 24-hour live feed surveillance known as “Blue Watch” that’s transmitted back to headquarters.

Next: These can help in an emergency.
