Interesting to note that even in such a brief clip (twenty-three seconds), the snakes are so maneuverable in flight that the cameras can't keep up with them.
Mildly disturbing to find that the researcher's project is being funded by the Department of Defense. While it's a better use of money than most of the stuff they get up to, the idea they might want to 'weaponize' flying snakes is mildly disturbing.
