There was a (and maybe still is) a B-17 flying out of Springbank airport.
Seems crazy, with the hovering and all, but it would certainly look different than any airplanes we normally see around here/around now. Something moving slowly towards or away from you might look like it's hovering.
The one that was here has a red tail and wing tips, and it is shiny.
