The entrance to the abyss is 300 meters above sea level. Below it, a dry chasm descends 70 meters, then begins to flood. If the robot penetrated to a depth of 450 meters below the surface (and the jet was not at the bottom at all), it means that it found itself 220 meters below the level of the world prize. So what? Of course, because of this, neither bread, nor taxes, nor gasoline, nor electricity will be discounted. But say the same about Emsi. You about equal research.
