At 18.30 i've saw 2 lights in the sky in the nice sunny afternoon in the garden. i was with my girlfriend,girlfriend sister and next door neighbour at the time.When i saw the lights i thought they were stars but the time was 18.15 unusual.Then one of the bottom start to move,then i said to my girlfriend to look up.She looked and said "they are more then 2,is one more.So,the bottom one start to move,the middle stayed stationary and 3 start moving very fast across the sky living the others.We all start to follow the one who left for 10-15 min,when we lost sight of it we looked back for the last two and they gone. after i went upstairs and record a video saying what i saw. i never seen something like that beforehand. was amazing and i'm so glad.Those things where higher in the sky,probably on the commercial aeroplanes highs
