Apparently visitors from other worlds are also interested in Niagara Falls!
From The Canadian:
On 15 July, UFO specialised website MUFON.com received an anonymous report about a mysterious event that occurred three days before, on 12 July. According to this report, “two large rectangles” were seen moving across the Ontarian sky.
“I am a Bellman at one of the major hotels right near the falls”, started his relate the unknown witness. He said he was looking through “the window of the 43rd floor while waiting for the elevator” when he “noticed two large Rectangles that would almost pass for solar panels hovering in the sky”.
