I don't think it's reasonable to assume it belongs to the US Government under the condition that these objects are confirmed to be real and capable of pulling, say 100G. I think that reality, if confirmed, would leave us rather short on low-surprise explanations fully consistent with it.

If it's confirmed that these objects are performing controlled maneuvers at 100Gs, then that would also confirm such a thing is physically possible here on Earth. Why would we need to make the leap that someone somewhere else must have brought them here?

[gfodor]

I didn't. But if these are determined to be solid objects performing 100G then it's very, very unlikely humans have developed this technology, particularly if the world's militaries explicitly deny it.

Saying humans didn't create it is a lot different than saying anything about where it came from.
