Thank you for the explanation Hesperides- this object is truly strange! It looks like it could be made of metal, not like a bird or a bug.I´ve been raised in Switzerland, very near of the area of ruins where both pics were shot (like 25 miles away).
Both pics were shot on July 26th. of this year within a very short time span, 6 seconds at most but probably much less, explains the father who took the pics of his little girl. So that whatever the flying object was, it went by very fast as it doesn´t show up any more in the second pic. The weather was clear and sunny, no wind.
The video owner draws the attention on the two upper round and equal structures that look quite interesting, adding that the shape of this object doesn´t bear any ressemblance with ballons or a montgolfiere.
Thank you Sirius for the video, this object is quite strange. The shape reminds that of a rock, but of course, we can´t rely on our cameras with flying objects.
