Continuity mistake: The Visitor craft that Mike and Ham capture is not the same type that is seen later entering the hangar. The first one is a small shuttle, the second is a transport, distinguishable by the windows on the side. (00:20:10)
Continuity mistake: When Mike radios Elias he identifies himself as 'wilderness' calling 'Shiloh'. When Elias acknowledges, he also identifies himself as 'wilderness' instead of 'Shiloh'. (00:33:20)
Continuity mistake: When Kyle and Sarah arrive to help Mike and Ham, they drive through a group of Visitor guards, who all dive onto the embankment out of the way. But two seconds later, two of the guards are back on the dirt track. (00:35:40)
