The Alpha Log Recorder (the trolley with the yellow wheels) disappears from Command Center immediately after Brian's departure. In the initial scenes (while Helena is recording on it), a filing shelf is located where it stands.
As Brian, Helena, Koenig and the two guards leave the travel tube to go to Command Center, we can see Koenig's hands in one shot (his arm behind Helena), but they are in his pockets in the next shot. Thanks to Thomas.
When Koenig and Helena are first forced towards the airlock, the emergency button inside the airlock is not present in Helena's airlock. It only appears after she has entered the airlock.
Brian's antenna is much longer when he's dangling from the Swift exterior.
In the epilogue, Brian is seen still dangling from the Swift exterior, which means that the ship is still in space. Presumably they must have docked in space with the Eagle to transfer Koenig, Helena and Maya. Why didn't Koenig take the Swift back to Alpha? Thanks to Thomas.
