Thanks for taking the time to reply Rachel. It's encouraging to see that others are noticing what is happening too. I see similar trails and particles falling through the air down in South West England. Skywatching has become a bit of an obsession with me and the sight of a almost white sky filled with haze that blocks the sun really pisses me off which means I am pissed off quite a lot.
I'm following you now, so I'll look out for your posts on this topic in the future.
Take it easy
