A very large bowl-shaped UFO seen near a beach, with a blue light rouding it and making a humming noise...I was at my beach house near Aveiro and I woke up. I saw a strange blued light coming from outside and I went to the dinning room to see what was making that light (the view from the room is a river that ends on the sea, at the other side of the house). I saw an enormous object over the river (about 15 meters large) that had the shape of a bowl turned upside down. It was dark silver and emited that blue light. The object was making a kind of humming noise. It stand over there about 25-30 minutes just as it was paralyzed and then it started moving not very fast to the sea. It was very close to the houses, so I could see it clearly. I never told this to anyone till last week I was talking with some friends and two of them I don't knew before started telling that on August 2001 they were at a beach party in Aveiro and they saw exactly the same object coming from the river and passed over them till the sea where suddendly disappeared! As I told before they saw the same light but they didn't hear the humming noise. I wasn't a person that used to believe on this kind of things, and in fact I didn't, but that day changed my way of thinking forever! I'll send a drawing and a map of the zone I hope it can help.((NUFORC Note: Date is approximate. PD))
