[00:00:00]Commercial jets fly at around 35,000 ft, but why?

[00:00:05]Closer to the ground, thick air creates more drag and wastes fuel.

[00:00:10]Higher up, the air becomes [music] thinner, helping planes fly faster while using less fuel.

[00:00:16]But flying too high would starve the engines of oxygen. That's why 35,000 ft is the perfect engineering sweet spot.
