Plan: Fly over the Mount Doom on an Eagle and drop the ring in the lava.
Flaws: Frodo might not drop it.
Plan: Create a time machine and stop Sauron from making the ring.
Flaws: That would take a loooooooooooooooong time.
Plan: Pretend to be on Sauron's side then when you’re near Mount Doom throw in the ring.
Flaws: Sauron would take the ring before you got that chance
Plan: Have people go into Mordor and reroute the lavas flow to a safe place where Frodo can throw the ring in easily.
Flaws: The number of people it would take to do that wouldn’t go unnoticed, and won't that take to long to?
Plan: Have Tom Bombadil take the ring into Mordor since he is not affected by it and has power that Frodo doesn't.
Flaws: Tom Bombadil refused.
Plan: Bring the Army of the Dead into Mordor and kill all the armies of Mordor then have Frodo destroy the ring.
Flaws: Aragorn wasn't thinking when he made the deal with the King of the Dead
Plan: Call numerous people the Ring Bearer (But have only one) and send them different directions to confuse Sauron and divert his attention from "Ring bearer" to "Ring bearer".
Flaws: No volunteers stepped forward to pretend to be the Ring Bearer, who would want Sauron's eye on them and possibly the Nazgul after them?
Plan: Leave Middle Earth and travel to the undying lands
Flaws: It's immpossible...
Plan: Give Sauron the ring.
Flaws: Who would want Sauron ruling over them?
Plan: Give the ring to Gondor to use for good.
Flaws: In the end it wouldn't be used for good.
Plan: Find another place other than Mount Doom to destroy the ring.
Flaws: There is no other place.
Plan: Talk Sauron out of his want to take over the world and talk him into living peacefully
Flaws: Sauron wouldn't listen, he was to busy searching for the ring
Plan: Try to convince all of Sauron's armies and followers to come onto your side then go into Mordor easily.
Flaws: They weren't being persuaded.
Plan: Make a fake ring and go to Sauron and give it to him, while Frodo takes the real ring and destroys it.
Flaws: Sauron could tell that it wasn't the real ring
Plan: Ignore the Ring, it can't do that much harm... can it?
Flaws: They all sat there staring at the ring.
Plan: Destroy Sauron so he can’t use the ring.
Flaws: He can only be destroyed when the ring is destroyed.
Plan: Waylaid a Nazgul while he's searching for a ring, dress up as him, steal his mount and go into Mordor easily.
Flaws: How do you waylaid a Nazgul and keep him someplace?
Plan: Travel a longer route to Mordor to throw Sauron off.
Flaws: What would that accomplish in the long run?
Plan: Throw the ring faaaaaaaaaaaaaaar away and into the sea.
Flaws: It will somehow
be found again
Plan: Flip ahead in the books and see how it all ends and what to do.
Flaws: They don't have the books
