I installed the app a while back.
I was happy to find that I wasn’t the only person who had seen the huge black triangle.
And no, I do not think it was “ aliens “.
I waved at it.
Yes, I also saw them, two huge triangle craft maneuvering together gracefully, as if weightless, at about 3,500 feet in perfectly clear daylight. Only the ones I saw were not black, but orange, like a traffic cone. They followed a major highway briefly, then tumbled off to the northwest. I am sure they were ours.
