It's not a plane. It looks like a bird. I slowed the video down right as it came in to frame and you can see it flapping in the three frames it's in. It moves up and down from frame to frame.

Agreed Zaphod. Looks like a bird passing by to me.

Hadn't seen that video before though...good find.

Thanks for makng me actually watch the video. A Helo and a small darty bird, perhaps a swallow or something, pretty close to the camera. Didn't get all scientific, but that's what it looks like. So yeah in a sense, two aircraft.

if thats a bird, its fast..

Or, and this is a stretch here, it's closer to the camera, so it APPEARS to go by really really fast, when in fact it's a perspective thing.
