No. The ‘spray’ spreads out, joins and a bright blue perfectly cloudless, sunny day turns gray in a matter of hours.
we’ve noticed that crap too
You can spot the trolls ... it is not water that they are spraying. Go to geoengineeringwatch.org. They have followed and sampled what they are spraying from those aircraft and it is not water ... aluminum, plastic, magnesium, etc.
I have witnessed this phenomena. Where I live the normal air traffic patters are high altitude planes on a SW heading and lower altitude on a NW heading towards the local airport. But in all cases, the air travel is parallel.
On a couple of odd occasions, the air traffic was flying in a grid formation at middle atltitudes, and yes, the entire sky quickly filled in turned completely grey.
I have no idea if anything nefarious was at hand, or whether they were weather modification experiments. Just what I observed.
