Red light in the sky, the object moved at speed from one place to another, then vanishdLocation, Europe, Croatia, city Zadar, 18.05.2011. Around 4 am local time I saw something I think is UFO, it was an object with red colour that was first falling down then going away in a sort of concentric or elipting circles, it is hard to precisely describe((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information.
