Lay on the sofa watching tv,I saw red lights out of the corner of my eye, I live on the 13th floor and thought it was a firework initially, untill I looked directly at it. I jumped up and grabbed my pda to try and record it, as I knew instantly it wasn’t a plane or helicopter, I have lived on the 13th for 16 years and have saw countless planes and helicopters, I knew instantly it was neither, it took me approx 5-10 seconds to get on the balcony by which time it was too far in the distance for pda to capture, I could no longer see the red lights but could see 2 white lights in the air, like car lights which then disappeared, there was no sound at all.
