im being serious, Sauron was looking for the Ring because it was the means for him to regain power and his full form. he was stuck with the eye and his minions to do the leg work. If the Eagles popped in all of a sudden and said "Surprise motherfucker" . Sauron's eye might be able to cast befuddle on one or two of them. but the rest will just scoot in drop the ring off at Mt Doom and be like, hahah pwned! and be long gone before the orcs or goblins had time to march over there. and i would also like to add something else if the Eagles were not to be trusted with the Ring, they could have just flown Frodo and Gandalf there late at night and be back home before second breakfast.
