What Goes Around, Comes Around - S3-E18
Plot hole: Tess sends Jack an airline ticket to visit her in Australia. The ticket reads 'From: Eureka, Oregon, To: Sydney Australia.' Seems odd that a commercial carrier would have a terminal in the most secret town in America. Eureka is a town created by the US government for its top scientists to experiment with new technologies. It is made nearly invisible from the outside by giant holograms. Very few non-residents even know of its existence.
Suggested correction: There's nothing to suggest Eureka has a terminal open to the public or other commercial airlines. In fact, the airline is named CircumGlobal which is probably not a coincidence that it shares part of its name with Global Dynamics. It could be a private airline only for Eureka staff and citizens.
Continuity mistake: Henry talks about Eureka installing it's first traffic light but there has always been a traffic light in Eureka.
Suggested correction: The episodes in the first season were aired out of order. The previous episode that showed the traffic light was produced after "Blink."
The light is in every episode including the first one.
Then I would suggest trying to submit a screen shot because I never saw the traffic light on Main and Archimedes in the first episode.
