Me and my friends were on a campingg place not far from a river were we always chill. We do this ever year once in the summer. In the evening we go to the river make a camping fire and hang out together. We were all like 18 to 19 y/o. It was about midnight when we watched the sky to find starsymbols. When I directly watched at the opposide of the river, above the hills i noticed some of the stars were moving. I thought my eyes were mistaken me so I asked the others and they saw it it too. The longer we stared at the lights the more they moved. It were about 10 but i cant say exactly because some of them went on and of. they were moving right above us. they were pretty fast, faster as a plane or jet wouldve been. suddenly when the were bihind us they went even faster till they dissapeared in the horiozon. just a couple of seconds after that 3 planes flew the same track as the lights flew. they werent normal planes they flew way too low. it were like military jets or something like that. while i was watching them i was like paralyzed i didnt even think of moving but i was very scared. non of the others said a word or moved normally you would excpect 7 teenagers to instantly grab their smartphones and take pictures but we were like paralyzed. we didnt speak much about it and after the evening we never talked about it again.
