So going back to contrails. The streamers of white that you see behind an aircraft isn’t smoke from engines, but what happens when water in jet exhaust mixes with wet cold air, condenses and freezes into ice crystals. Contrails are actually a type of cirrus cloud – another nugget of wisdom my dad shared with me – and occur at high altitudes, say at 25,000 to 40,000 ft. Since commercial airliners generally reach the 30,000 ft. above safety on the ground mark, and taking into consideration those 100,000 flights that happen globally, you’re bound to see contrails often, if not several simultaneously.
“That looks like a sharp.”
What about you? Any interesting contrail pattern sightings? If you have photographs, please share!
