crystals in the atmosphere, which he likened to clouds and possibly like the rings of Saturn. The Voyager probe later confirmed the existence of the rings of Jupiter, although these rings are not in the planet's atmosphere. However, Swann's claim that crystals are present in the atmosphere is supported by observations by NASA's Galileo spacecraft of clouds of ammonia ice crystals in the northwest corner of Jupiter's Great Red Spot. The following are Swann's own version of his statements from 1995, 22 years later than the 1973 experiments took place: [6:06:20] Very high in the atmosphere there are crystals ... they glitter. Maybe the stripes are like bands of crystals, maybe like rings of Saturn, though not far out like that. Very close within the atmosphere. [Unintelligible sentence.] I bet you they'll reflect radio probes. Is that possible if you had a cloud of crystals that were assaulted by different radio waves? [6:08:00] Now I'll go down through. It feels really good there [laughs]. I said that before, didn't I? Inside those cloud layers, those crystal layers, they look beautiful from the outside. From the inside they look like rolling gas clouds – eerie yellow light, rainbows. [6:10:20] I get the impression, though I don't see, that it's liquid. [6:10:55] Then I came through the cloud cover. The surface – it looks like sand dunes. They're made of very large grade crystals, so they slide. Tremendous winds, sort of like maybe the prevailing winds of Earth, but very close to the surface of Jupiter. From that view, the horizon looks orangish or rose-colored, but overhead it's kind of greenish-yellow. [6:12:35] If I look to the right there is an enormous mountain range. [6:14:45] I feel that there's liquid somewhere. Those mountains are very huge but they still don't poke up through the crystal cloud cover. You know I had a dream once something like this, where the cloud cover was a great arc ... sweeps over the entire heaven. Those grains which make that sand orange are quite large. They have a polished surface and they look something like amber or like obsidian but they're yellowish and not as heavy. The wind blows them. They slide along. [6:16:37] If I turn, the whole thing seems enormously flat. I mean, if I get the feeling that if a man stood on those sands, I think he would sink into them [laughs].
