are you saying ONE plane left that trail and no others? or that around 11AM all the planes started leaving trails?
Discussion
The latter.
And you don't think the most parsimonious explanation for that is air temperature changing throughout the day (thus effecting all air traffic at a given altitude equally)?
You think the better explanation is that all the geoengineering planes were scheduled for 11AM?
Yes
Alrighty then..
