The clip is known online as the supposed last words of Takuma Nakamura of the Tohoku University Windnauts, the student team behind human-powered aircraft projects tied to Japan's birdman scene. Tagged by uploaders as a famous line, it preserves the moment his mid-flight question about his speed, roughly how many kilos he was doing, is answered by the dobon of the aircraft hitting the water. Shared as a short fail meme, it endures because the doomed question followed by an instant splash works as a ready-made punchline for any ambitious plan collapsing.
