Ask yourself this question, how can they honestly make that statement?

They have absolutely zero proof of that being true, or false for that matter. For they have not secured even one of these UFO's to scrutinize it.

Thus it is an empty statement devoid of any factual evidence to support their claim. They are in reality only asserting as a hypothesis with that statement.

For they have not secured even one of these UFO's to scrutinize it.

General Jesse Marcel would disagree.

Is the Pentagon keeping you in the loop re: their classified work?

In a world where no one knows anything, you seem to know an awful lot.;-)
