Title: Things that make you say Mmmmm?
Post by: Paul Taylor on February 11, 2025, 03:43:30 PM: 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?

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

Post by: Brian Hampton on February 11, 2025, 06:20:26 PM: 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.
