"FiveNineFive
Because the Eagles were very powerful beings and Sauron would have sensed them.
I’m sure it could have dropped them half way."
I'm just wondering where, even to Lothlorien and so avoid Caradhras and the Mines of Moria. You perhaps wouldn't have needed the same number as part of the Fellowship, but I still think spies would have spotted them and passed word early on. Secrecy (and distraction) was needed for them to have a chance.
However. that would have meant Gandalf 'survived' (he did survive, obviously) but I mean to go with them. He needed to be out of the picture, door a time, for the rest of the story to unfold as it did. Similarly to when Gandalf was held prisoner by Saruman, and possibly even at the end during the scouring of the Shire.
I think this needs its own thread!
P.S. pp who mentioned it was too long! I thought it wasn't long enough! The addition of Tom Bombadil and the scouring of the Shire would have been very welcome, in my opinion.
