Earlier this year (3/26/07) I arrived on a flight into IAD in the evening. As the "lunar rover" rounded a corner on its way to the main terminal I saw this giant tail fin and immediately thought 380 (plus it said A380 on it - duh). It was all lit up and cordoned off with security vehicles at each corner, and the cargo hold was open - simply huge. The rover was really packed, and most people didn't even seem to notice the plane, other than the travel professionals who were clearly all over it.
I have little interest in flying on this behemoth for regular travel, but if I'd been offered the chance that night, in spite of just winding up a long trip, I would have been headed out of town in a heartbeat.
