For your benefit I will attempt to find the sources. Although sometimes I heard such stories from going to SRF lectures. I one such account Paramahansa Yogananda took a devotee to the desert because of his fascination for UFOs. When there the guru and the devotee witnessed a sky full of UFOs and he told the devotee that his curiosity has been satisfied so to attempt to now satisfy his spiritual aspirations.
After all even Paramahansa Yogananda showed a devotee of his that there is much alien activity and spoke of human lives on different planets that suited the present evolution of their souls.
Where did you find that? I don't remember such details...
