Whether you believe that the aeroplane trails which are becoming more and more common and lasting longer and longer periods of time are a natural vapour trail formation, exhaust or chemical trailing for geo-engineering or more nefarious purposes is irrelevant.
The fact is that in recent years, aeroplanes have been leaving trails that cover the sky, causing overcast days out of fine ones, obscuring the sun. We breathe it in and it gets rained down on us.
So regardless of the cause, aeroplane travel has to be rethunk, me thinks. I do not utilise planes, so it would not worry me if they were all grounded, and it annoys me that I suffer their pollutants so others can enjoy the benefits.
Here are a few photos taken over Canberra Australia last month, when for the first month of Summer we had 3 clear sky days. 8 days into January, 2 for this month.
