I disagree with them about the Lord of the Rings.

In the Hobbit, Gandalf tried to get the Eagles to take them further on their journey, but they refused (I forget why). And there is no way they would let someone blindfold them.

But say that part of the plan worked. Mordor would be full of 10,000 -20,000 orcs. But far more dangerous would be the Ringwraiths riding their Fell Beast.

You may say, “In Return of the King, the Eagles attacked the Ringwraiths riding their Fell Beast.”

At that time, the Witch King was recently killed. Had he been alive it might have made a difference. But even if it didn’t here is the kicker. When the Eagles attacked, they were carrying no one on their backs or in their claws.

Had they had people on their backs, and/or in their claws there is no way they could have defended against the Ringwraiths riding their Fell Beast, especially blindfolded.

So I don’t think just flying into Mordor would have been a walk in the park.
