Narrative:

Total loss of yellow hydraulic system; leaving the green system and the emergency blue system. We declared an emergency and diverted to the nearest airport and landed uneventfully. The loss was due to a seal leaking in the wheel well. ATC was very helpful and got us on the ground without any delay. Everyone was professional; this was just one of those things that happen.
