Hi I agree the Aliens are cleaning our atmosphere, I had some photos sent to me for analysis, taken near Derby, England 2011. The first is a Mothership and then a closeup. The person was taking pics of chemtrails, the "flak" of which always appears purple when analysed (true colour)
When the closeup is processed an outline towards the Mothership can clearly be seen and what appears to be energy striations. I attached a few chemtrail photos just to show the fallout. Happy breathing, John
