I remember one time I was outside with my fraternity brother at night. We saw a large triangle of three red lights in the sky. No blinking. No sound. Just slowly moving. And then, shooooooo! It sped off at an insanely high speed (again no noise). Like, it traveled as fast as a shooting star across the sky. The triangle went that fast. Don’t know what the fuck that was, but we were both freaked out. Now, if that were human, they wouldnt be able to withstand the G forces of going so slow and then accelerating to such speeds so quickly.
