I had been wondering to myself if it was possible someone could have gotten hold of the Nine Rings and thrown them into Mount Doom without falling to their lure. However, I'm wondering, what became of the Nazgul and the Nine Rings when Sauron fell (the first time, not the final time)? If they went into the Shadow Realm, did they take their Nine Rings with them, or were the Nine Rings laying around somewhere till the Nazgul rose again and took them? Or did Sauron have the Nine Rings, perhaps because the Nazgul no longer needed to wear them for him to control them? And if Sauron had the Nine Rings, why did Isildur not take them as well? If someone had been able to get ahold of the Nine Rings and throw them into Mount Doom (It seems plausible that if Mount Doom could destroy the One Ring, it could destroy the Nine Rings as well, and presumably the Seven Rings, though I'm not sure, as Sauron never made them, if it could have destroyed the Three Rings, though perhaps it could, as dragon fire supposedly could destroy the Great Rings, and Mount Doom was probably as hot as dragon fire.), they could have saved the Fellowship, especially Frodo and Merry, a lot of pain.
