Much higher-grade lunacy than the grim-and-evangelical UFOlogy we got a decade later. (Especially Streiber, which I grew up reading.)
Was surprised to see how incredibly racist Keel’s description of the (“Mongoloid,” and “foreign faced” and “dark, not Negroid”) Men in Black was. That MIB stood in for overtly racialized xenophobic anxiety seems to have been forgotten as MIB have become emblematic of Big Government or whatever, which is odd.
