That day I was rushing to go to work walking through Ksenopulou street New Psychiko Athens towards the tube station around 19.45 pm. I have experienced those lights back in the day in London twice and once again in Greece but this time was so much more intense. The first lights were 3 in a triangular formation flying very slow and very low I mean very low and when they reached the ministry of defence the kinda disappeared flying higher..So I thought I will move on , but it wasn't over 12-14 more followed up in a que and a couple of those flew even lower! I am not even gonna describe the classic phenomenon (no sound, no engine, looks like a fire ball) there are thousands of descriptions online that all match but I will say when I was there my phone had perfect 5 bars of sygnal but I couldn't make any phone calls or messages. I couldn't take a picture with my cheap camera phone but we re not here to convince people we know very well it's real! Feel free to contact me for further information. It was so intense I am surprised how the Greek public is totally blind!
