About 5 years ago I was at home in Aarhus, Denmark, expecting a visit from a
friend. There's a buzz at the intercom, and I go out to let him in. But I can hear he's
not opening the door downstairs, so I stick my head out of the window to see what's up.
My friend is standing downstairs alright and I ask him why he doesn't come in. He just
pointed up and said: Look at that! And there above the houses this big metal tube was
silently floating across the street. It was actually flying this low, about 75' over the
roof. It was there for a few minutes, it just floated across the street and disappeared
behind the house you see in the picture.
