Character mistake: The Eagle Koenig flies is called Eagle One. However, the number on the door behind him is plainly a four, meaning Eagle Four.
Suggested correction: This happens a lot. The number on the door is not the number of the Eagle, it's the number of the command module. The super structure and drive systems are Eagle One. Even then, there has been several Eagle Ones destroyed or lost. Eagle One is assigned its designation by the head of Recon, Alan Carter.
Other mistake: At Waste Area 2, as Nordstrum throws Steiner, his visor flips open.
Visible crew/equipment: In the beginning when the camera enters room 3C with the plants, a shadow of the cameraman can be seen on the door frame. (00:02:05)
The Testament of Arkadia - S1-E23
Continuity mistake: As Paul calls to all sections, he's standing over a console, but on the screens, there's a wall directly behind him, and the shadow of his head can be seen over his left shoulder.
Continuity mistake: As the experiment recreation progresses, and Helena identifies the spirit, the spirit appears with damage on the left side of its face, and a yellow sleeve on its right arm. When the camera is close up to the spirit, the damage and yellow sleeve change sides.
Space Brain - S1-E21
Continuity mistake: The number on Kelly's suit was 4. As Paul went to go out after Kelly, you see the number 4 on the control panel, then when he nears Kelly, it's changed to 3, suggesting the shot of the exiting person was re-used.
Continuity mistake: As the scene in Main Control gets blurrier as Koenig spins around, the part in his hair is first on the left, then on the right, then back on the left.
Other mistake: As the camera pans around to look in the cockpit, the wound on Koenig's head is easily seen as a bad blending job. The edges of the prosthetic are visible.
Other mistake: In the beginning, the Eagle was moving away from the alien planet, and as such, should have crash landed facing away from the planet. However, it was facing the direction it came from. If it traveled a fairly straight line, (and the trajectory suggests it did) then it should have crashed with the rear end facing the planet.
Continuity mistake: As Helena is tapping on the key panel, the row of black keys goes from second on the right to second on the left and back, showing the shot was reversed.
Revealing mistake: As the "dead" companion lies in the coffin, you can see him breathing.
Revealing mistake: As the camera looks at the exhaust port of the probe's engine, there's water dripping off the bottom, showing the stream is water vapor.
Continuity mistake: As the alien struggles with the security personnel, it's easy to tell the alien actor and the stunt double. The hair color and style change between distance and close up shots.
Continuity mistake: The panel Tony hits with a tomahawk in his quarters first appears to be molded plastic, then in a close up, appears to be painted wood, as the wood grain where the panel above is smooth.
Revealing mistake: As Koenig tells of the attack, his feet are passing by the "dead" Mike Baxter. As they pass, Baxter's eyes flicker for a second.
Revealing mistake: As the Voyager probe lands, the control wire lowering it is visible.
Revealing mistake: As the Eagles take off from Piri, the wires used on the models to "fly" are easily seen.
Alpha Child - S1-E7
Revealing mistake: As the alien ship approaches Alpha on screen, there is a round, blank area where the model moves, and as the vessel nears the camera, the edge of the cell used for the picture of the vessel is visible.
Alpha Child - S1-E7
Revealing mistake: As Jackie is drawing, Koenig's face comes up on the communicator. As the screen goes from the idle/test pattern screen to the identity screen, you can see the picture jump, suggesting there was a pause in filming to allow the unit with the idle screen and the picture screen to be swapped out.
Other mistake: As Zoref pulls the reactor door open, the wig wrinkles up on the back of his neck. Also, when the door is half way open, he's still holding it, then he's suddenly several feet away from it when it's still swinging open.
