Over 20 people where in public park watching red birds in trees when we saw very high and far up that white worm making very extrange movements in the sky,some of us ran to get binoculars but nobody could take a picture of it since it could not be reached by celular cameras because it was so high,even 3 planes passed under it, all people was scared, and even one old lady asked us to go to church, after one hour it moved very far away until it disapeared from our sigth, at first we thougth it was a big ballon,but we discharged it because it was so high, that no ballons could reach that high,many people in the park came and saw it and ran away scared, cause they thougth it eventually may land.We checked on TV and Radio news, but nobody reported or filmrd it, any how all of us get together evry week since then to see if we can watch again this phenomenom Also we saw some 4 spheres cominng from far away to meet this big worm and then disapear.Until now we do not know what was it.
