Crescent moon shaped?
I'm reminded of the 'Engineer ships' from the Aliens franchise which actually do a good job of genuinely looking otherworldly.
David Grusch told Fox News today that he has seen crash-retrieval photos of various recovered UFOs, and wants the administration to release this information to the public.
"A lot of it was lenticular discs, some was crescent-moon-shaped, I call it the flattened sunfish. There's a bunch of different morphologies that the US government has recovered from eggs, the discs, to crescent moon, boomerang-type vehicles... that have landed or crashed on the surface of the earth."
