Here's one of the Airstreams up in St Louis in the Edward Jones Dome in 2011 for the First Robotics Championship Event. NASA provides the internal communications network and it all funnels through this Airstream. Insides have pretty much been trashed and it's very utilitarian inside holding network support equipment. The NASA folks assigned to this event hold their breath in driving this some distance from Fla, due to its age. It needs maintenance.
The year after it didn't make the trip due to some mechanical issues. I'm not sure if it made it this year since I'm no longer working at the convention center.
