I read "The Day After Roswell" by Philip J. Corso, and I seem to remember a section of the book talking about the aliens lacking a digestive
system.
I searched and found
www.bibliotecapleyades.net...
"What did intrigue those who inspected the aircraft once it was shipped to Wright Field was the complete absence of any food preparation facilities.
Nor were there any stored foodstuffs on board.
...Of specific interest was the fluid that served as blood but also seemed to regulate bodily functions in much the same way glandular secretions do
for the human body. In these biological entities, the blood system and lymphatic systems seem to have been combined. And if an exchange of nutrients
and waste occurred within their systems, that exchange could have only taken place through the creature’s skin or the outer protective covering they
wore because there were no digestive or waste systems.
...
The Walter Reed doctors were also fascinated by the nature of the creature’s inner skin. It resembled, although their preliminary reports didn’t
go into any chemical analysis, a thin layer of fatty tissue unlike any they’d ever seen before. And it was completely permeable, as if it were
constantly exchanging chemicals back and forth with the combination blood/lymphatic system. Was this the way the creatures nourished themselves during
their journeys and was this how waste was processed? The very small mouths and the lack of a human digestive system troubled the doctors at first
because they didn’t know how these things were sustained. But their hypothesis that they processed chemicals released from their skin and maybe even
recirculated waste chemicals would have explained the lack of any food preparation or waste processing facilities on the craft. I speculated, however,
that they didn’t require food or facilities for waste disposal because they weren’t actual life forms, only a kind of robot or android.
Another explanation, of course, suggested by the engineers at Wright Field, is that there would have been no need for food preparation facilities had
this craft been only a small scout ship that didn’t venture far from a larger craft. The creatures’ low metabolism meant that they could survive
extended periods away from the main craft by subsisting on some form of military prepackaged foods until they returned to base. Neither the Wright
Field engineers nor the Walter Reed medical examiners had an explanation for the lack of waste disposal on board the craft, nor could they explain how
the creatures’ waste was processed. Maybe I was speculating too far about robots or androids when I was writing my report for General Trudeau, but I
kept thinking, also, that the skin analysis that I was reading sounded more akin to the skin of a houseplant than the skin of a human being. That,
too, could have been another explanation for the lack of food or waste facilities. "

they either know its false and are spreading lies deliberately... or
there a little short in the mental department.
