146 At 7:40 pm EST (after dark) on 2/23/23, W. Virginia resident reports that a small plane flying overhead was dropping thick white powder on her house. At the same time reports came in from other residents across WV and MD of white powder falling from the sky. Ash from Palestine or something else?

Poly vinyl chloride (PVC)?
"Pure polyvinyl chloride is a white, brittle solid."
Production "About 80% of production involves suspension polymerization."
https://en.m.wikipedia.org/wiki/Polyvinyl_chloride
"Suspension polymerization is a heterogeneous radical polymerization process that uses mechanical agitation to mix a monomer or mixture of monomers in a liquid phase, such as water, while the monomers polymerize, forming spheres of polymer."

Hmmm.
