I feel ya.. same here I cant believe when its happening like you showed above that people still are not questioning what is above their heads. Here in Budapest its extremely hot and especially that nasty heat after the sky has been filled up like in your pictures.. you can see the lines get blurry just by watching a few minutes.. its obvious and those planes seem to fly as if the make a dome above us.. damn high (sometimes vertical ) and way different than normal planes.. I cant even remember a day without witnessing the sky art above me. Its so rare..
