Looks like the chemtrail activism is working, because why else would TPTB be doing stuff like this??
US space agency-led scientists flew small, instrumented, chase planes directly in the exhaust plume of a big jet to measure the sorts of gases and particles being thrown out.
The data suggests aircraft burning a mix of aviation kerosene and biofuel could reduce their climate impact.
This would come from a substantial reduction in the production of the sooty particles that make contrails.
"Those soot particles serve as nuclei for water vapour in the very cold atmosphere to condense on and for the artificial-looking linear contrails that we see when we look out the window," explained Richard Moore from Nasa's Langley Research Center.
