The biggest plot hole in The Lord of the Rings is arguably “why not use the Eagles to get to Mordor?”
But imagine an alternate universe where Tolkien wrote LotR, with the same internal consistency, except the Fellowship of the Ring ride the Eagles to Mount Doom…
Could they get there? You bet! But it’s not as simple as it sounds. How do the Fellowship get in touch with the Eagles? Which way would they go? Who would go? How long would it take? What precautions would they take? How would they get over the mountains and past the winged Nazgûl?
All these questions and more are answered at Flying the Eagles to Mordor – A ‘How-To’ Guide.
Seriously, “Fly You Fools!!”
