Strange object in Poland , 97' winterI've seen this object near the shop. I couldn't remember the date of this event, probably 97' winter. The object has shape like triangle with few red/green lights on the bottom. Object made a sound like beep-beep but only few times. Duration of this event - about 10 seconds, maybe a little longer. The object was hanging about 20meters over the ground/my head((NUFORC Note: Witness indicates that date is approximate. PD))
