Waco 2017:

Group of white dots moving fast followed shortly by a smaller group of the same. All disappeared at the same spot in the sky as if going behind a curtain.

It was about 540 in the afternoon with clear skies. I happened to look up and saw what I at first thought was a flock of white birds very high up. As I watched I felt that it want birds due to the speed and altitude. There were between a dozen and twenty of these white dots moving together as a group but randomly, not in formation. The individual dots moved a bit in relation to one another within the group. Two or maybe three of the dots from kinda in the middle of the group did some sort of a flip or loop kinda move to the outside of the group and back into position at the rear of the group. At that point the objects disappeared as they crossed a certain point in the sky, as if going behind a curtain. I was a bit awestruck dumbfounded whatever....it didn't make sense. I kept looking up at where they were and a few seconds later another group of maybe five or seven of these objects came on the same path as the first and disappeared at the same spot.

March 2011 in Japan:

It's burning... what is that?
It ain't a plane. Is it a comet?
Better not be an asteroid coming over here!
It's dying.
Had you heard about all the earthquakes that are happening here?
