The next day at home, we heard the neighbors shouting we should look up. All of us five family members went to the roof only to see another silver object overhead. It also sat in one place for a while and then sped off at great speed. OK, now what was it that all the neighbors and we saw? I have no answer yet, but they certainly were not balloons.
Wow, a post like that on this thread and no one replied? That is a pretty amazing sighting.
Quix - ping.
Balloons -- caught in an updraft. You were correct in your first conclusion.
There's a FREEPER who ran into some photos at the USA shop of some Mexico City relatives from that sighting series. Crystal clear photos. We are trying to see if and when he might travel back to that USA location and see if he can get copies and post them.
