Things that make you say Mmmmm?

Laying outside watching the sunset.
One plane flying south is leaving a Connie <sp?> trail. Plane passed by looked about the same altitude-+ a foot and no Connie trail. Why is that?

[Gerald Arana]

Duh! One is IC and the other is 'lectric!

I think they are called contrails.

I think they are called contrails.

Yea those.

[Matt Colan]

They’re at different altitudes. Looking from the ground, I don’t think many people can discern airplanes within 5000ft of each other unless you had FlightAware or any other airplane tracking app with you to verify

Actually 'condensation trail'. Contrail for short. The 2 planes had to have been at significantly different altitudes.

[Brian Hampton]

Contrail is a shortened term for condensation trail. When the water from the exhaust after combustion mixes with local conditions (altitude/temperatures) it becomes visible as a cloud which can vary from horizon to horizon or be intermittent. Even a difference in altitude of a thousand feet can have totally different local temperatures. Forget the CT's about "chemtrails", it's just water vapour like the steam you see from the exhaust pipe when you start your car on cold days.
