B747-437B!
Can't imagine what it's like to live in a green zone for an extended amount of time, but would have liked to walk around there for a couple of hours. Don't really want to get denied boarding or being stuck inside the airport for 8 hours, so maybe I will have to give this one a miss.
(unless someone can confirm that no (transit) visa is necessary to walk around in the green zone)
