Wasn't one of these tictac anomalies seen going into and coming out of the ocean at supersonic speeds? Water isn't very compressible and hitting the water at modest speeds is often a death sentence for bridge jumpers and can completely annihilate a falling airplane.

But here's something large, fast, and observed going into an incompressible liquid as if it wasn't even there.

Obviously if this is some sort of tech it is doing things we don't even think are possible according to known laws of physics. Which is interesting.
