Excellent, That's confirmation enough for me, thank you.


Ok, now another question. If a plane flies through a patch of really moist air(supersaturated), wouldn't the wingtips also produce a contrail? Like a fighter jet does at an airshow.

Reason I ask is there's a pic on the geoengineeringwatch site, that shows a plane that is clearly spraying aerosols, because there is nothing coming off the wingtips.
