Are these contrails?
The first two pictures are actually gifs. They were captured over the Netherlands. The first one features a boeing C17 with ‘contrail’ at cruise altitude.
The second plane is a A380. Do you see the difference in ‘chemtrail’?
The third picture was taken in the UK. The ‘smoke trails’ appears to mainly come from the tail of the plane instead of the engines.
Wake vortex? or new spaying technique? Tell me what you think please.
