But is completely absent in the satellite pic of the same contrail.

When was the satellite pic taken and from how far away? Distance and resolution (look at Doris Day close-ups) can obscure otherwise readily apparent details. If is the same contrail then the explanation for what is apparent as a detail in a photo taken from a relatively closer vantage point that does not appear in another photo must lie in the differences in conditions between the two photo sources. And please don't start in a Barney Fife-toned explanation of, "Well, we all know that military satellites can read the cancer-warning on a pack of cigarettes from an altitude of 90 miles so they should have no trouble at all with something a big as a contrail."

The sat pic was taken at 5:30 PM PST one minute before UPS 902 crossed Catalina. It is the one the NASA expert used to make his case for an airplane contrail. You would think if there was so much difference in the widening of the contrail from the ground it would still be evident in the sat pic.

I generally don't do that until someone else starts that kind of thing with me. So, since you started that with me ...
