I've seen four, I think, in the sky.
My husband has seen a lot more than I have.
Two of them were close and pretty big. Two were distant.
The first one was shiny and shaped like a triangle, but it looked like the bottom of an iron, that you iron clothes with.
The second was huge, a rectangle, dark color, no lights, with lots of things sticking out of it.
They were all in towns, with houses and trees around.
Not very remote.
Another I saw was a dark spot in the sky, like it should have been a light, but it was a shadow.
Another was a triangle, a dark shape, with lights on the corners.
It glided right over the road we were driving on, and glided back again the other way.
I remember more from the inside of crafts than from the outside.
