I was with my friends at the lake ��oderica near Koprivnica, Croatia. We set a camp and i layed down to the ground for a little rest. I remember like it was yesterday, the sky was very clear and full of stars and then after a few minutes 3-6 min. i noticed a bright dot, it was very far, almost at the edge of atmosphere. It was fast. I thought it is a fast jet but it was not blinking. straight direction from south to north and what hapened next shocked me. The thing changes direction on 90 degrees at that speed. I said to myself wtf! After it changed directiom it wanished 6 - 7 seconds after. It looked like it's gone up to the space. I will never forget this and I am sure it was not from earth cose it broke the laws of physics. unfortunately, my frinds didn's see this phenomenon.
