They called the "Foo fighters." (Pre-dating the rock group by many decades.)

Great stuff as ever, Don. But Foo Fighters are an integral aspect of Americana and American folklore in general, so what could be more fitting for a band to use the name? In fact, this really ought to be a folklore thread. The reality of the UFO phenomenon is perhaps less significant than the various traditions of cultural interpretation we see both in terms of psuedo-science and psuedo-religion. Like most people, I enjoy the mythos, the storytelling, the general lore that accumulates inspite of itself really.

There is a famous photo of a diminutive alien looking "person's" body being held up by one hand and appearing to stand between two 1947 army arimen officers.

Is this the one you're thinking of?

It's as iconic in Fortean circles as the Loys' Ape pic, though unlike the latter no one seems to know too much about it.
