Hello,Me my two sisters and my elder brother and his wife were chilling out after dinner at roof of my houselast night.My youger sister saw these lights and asked me first to have a look at that as im a physics post graduate so whe knows who to tell first about these abmornal lights. Abnormal because the lights were not in shape of any jet or plane. It was a straight line. The apeared in lower SW and with a curving directional change, they changed the shape in between this, the last of the lights came right of first three forming L-shape. Thenit dissapeared in coulds or dimmed tye lights so that we couldn't see them anymore. The time would be between 10:00 - 10:05 ( as i noticed the time of first appearance )First i saw it i thought about a jet or plane.But firslty , the area where i live is not a jet fly zone. Te last time i saw a jet was about 2-3 years ago.Secondly, the thing which mademe believe it abmormal was tgat the distances bw the lights were not perfect all the time.It doesnt mean they were moving weidely apart to and fro. It was like when you take 4 lights in your hand and walk, the distances bw the lights do not remain exact same.I have seen and heard many ufo stories so i know shich one to believe fake or real in first opinion. This one felt me like a real one. Thats why im reporting this.
