sounds like what Grusch was talking about
He claimed in response to Congressional questions that the U.S. has retrieved what he terms "non-human 'biologics"
From the other thread Jessica Beck-Stimpert alleged these things moved in ways underwater that shouldn't be possible from what we understand
The creatures displayed speeds of 70+ knots...
They didn't look real, they looked like computer animation or something...
We don't know how they were swimming, as they weren't wading, or moving their bodies the way a fish, or even a human would need to underwater...
maybe they did get samples and that's what Grusch was exposed to
and [we] even extended a robotic arm on the submersible, to try and get some kind of physical sample/DNA from the specimens...
maybe it's just a good LARP
