From Desmond Leslie's and George Adamski's book Flying Saucers Have Landed (1953), George Adamski describes an ET that he met in the southern California desert.
They then conversed on various subjects by gestures and telepathy, and this gentleman eventually went back to his RV-sized flying saucer and flew off. GA later named him Orthon.1. His trousers were not like mine. They were in style, much like ski trousers and with a passing thought I wondered why he wore such out here on the desert.
2. His hair was long; reaching to his shoulders, and was blowing in the wind as was mine. But this was not too strange for I have seen a number of men who wore their hair almost that long.
... it was however a friendly feeling toward the smiling young man standing there waiting for me to reach him.
The beauty of his form surpassed anything I had ever seen. And the pleasantness of his face freed me of all thought of my personal self.
The flesh of his hand to the touch of mine was like a baby’s, very delicate in texture, but firm and warm. His hands were slender, with long tapering fingers like the beautiful hands of an artistic woman. In fact, in different clothing he could easily have passed for an unusually beautiful woman; yet he definitely was a man.
His hair was sandy in colour and hung in beautiful waves to his shoulders, glistening more beautifully than any woman’s I have ever seen. And I remember a passing thought of how Earth women would enjoy having such beautiful hair as this man had. As I said before, he wore no protection over it and it was being blown by the winds.
His clothing was a one-piece garment which I had a feeling was a uniform worn by spacemen as they travel, like Earth men in various types of work wear uniforms to indicate their occupations.
GA claimed for the rest of his life that this was a physical encounter, not a psychic or etheric or whatever encounter. Desmond Leslie once claimed that GA once protested that his ET friends are not "goddamn spooks".
But from GA's description, Orthon looks much like some stereotypical angel. Admittedly, angels aren't known for wearing jumpsuits and traveling in vehicles, but there does seem to be a resemblance. There's also a resemblance in the form of meeting angels in out-of-the-way places. Mohammed meeting Gabriel in the mountains near Mecca, and Joseph Smith meeting Moroni in rural upstate New York.
