On a drawing "as we did se it" I was ca. 5 mm Observation made by two children at 12 and one adult women. Both children had no doubt of "something" was weary different from helicopter and aeroplane there fore they reacted by telling there observation as a question "what was that ?". The children were a bit frighten so I did not dug further in there observation. The woman wouldn't talk about it. Next day we heard that UFO observation in the days before was made in northern Italy. That's why I respond with this observation. We are from Denmark and was on vacation in Italy.
