An Airplane's Contrail

Looking down at an airplane producing its contrail. Looks like a scene from Firefly.

Unusual footage of an airplane producing its contrail, from above!
Also a reminder of the amount of CO2 it emits. What you see is water vapor, and for every molecule of water, there’s roughly one molecule of (invisible) CO2 as well.
Imagine all our CO2 emissions were visible! https://t.co/ktZIHxrc2E
