Whiffling: The Art of Flying Upside Down
https://www.amusingplanet.com/2021/0...side-down.html
Quote:
While it looks painful, such a maneuver is indeed possible and is a tried and tested way of braking, called whiffling. By turning the body upside down, the aerodynamics which usually give a bird lift during flying are inverted causing the bird to plummet towards the ground. Whiffling allows the bird to rapidly lose speed and height either for a fast landing or to throw off avian predators.
The behavior is seen in several species aside from geese including lesser yellowlegs, the black-tailed godwit, the northern lapwing, three species of scoter, and other members of the family Anatidae.

I was disappointed that it isn't a human/rocket hybrid, but extra point for the 1959 Cadillac tail lights.

I don't think the Go-One is "close." The front wheel openings could be done far better, and the windshield is a disaster for daily use. Plus, you won't be getting much exercise sitting in that greenhouse on a nice day.

Hard to see if they keep their heads upright, but it does seem so.

The half-roll suggests it's so. Else they'd have to snap their gaze like a pirouetting ice skater.

I have lived on a river for the past two years, and it's filled with geese year around...............chase them off my lawn etc............
The view out my kitchen sink window is of the river, plus I hang out on the deck all the time, and I've never noticed this phenomena.
I will be looking for it now, apparently it happens in the blink of an eye.
