It’s actually just a fish. This is a badass video of a flying fish staying aloft for 45 seconds. I don’t recall ever taking a good look at a flying fish; it’s amazing how much it resembles a toy glider.
The video is also cool because it takes place near Kagoshima, Japan, a place I’ve visited several times, and not so far from Kumamoto, where I lived for a couple years. Nothing reminds me of Japan more than funky fish.
Fugu, for example.
