Other mistake: With the red alert at MoonBase, all three Interceptors are launched with their loaded missiles. Then, as the UFO gets closer, the Interceptors are within range, yet Straker orders them not to intercept. However, when the three Interceptor pilots are told to return to MoonBase, all three Interceptors are inexplicably missing their missiles. (00:03:25 - 00:05:35)
Plot hole: The alien-possessed Mason steals Captain Lauritzen's fingerprints by pressing his fingertips to the captain's and "heat transferring" the prints. Big problems here: those prints would now be backwards and for the wrong hand. But when the computer later reads the prints, it fails to notice this and passes him through security as "Identity Correct." (00:23:30)
Revealing mistake: When Foster arrives at Straker's car, there's a black rod under the car's door holding it up that should not be there.
Revealing mistake: Straker and Foster take off for the moon in a large red hovercraft which, even though it's launching in broad daylight, doesn't cast any shadow. (00:12:00)
Flight Path - S1-E15
Revealing mistake: When the mobile-units leave the transport carrier, you can see that both are being "driven" by dolls. (00:22:00)
Visible crew/equipment: At MoonBase, when Nina announces the three UFO sightings, the shadow of the boom mic sweeps across the wall, above the monitor. (00:05:20)
Continuity mistake: In the opening scenes, the smudges and rips in Straker's black shirt keep appearing, disappearing and changing configurations between shots as he races through S.H.A.D.O. HQ and the Harlington-Straker studio lot. (00:04:30)
Revealing mistake: While Straker and Col. Lake enter the studio lot, they make a few stops, then exit the car; the silver metal rods holding the doors up are visible in a few shots. (00:16:50 - 00:18:50)
Revealing mistake: When Straker and Col. Lake stop to check out the frozen people (fixed like statues), Lake spots a bird frozen in midair, and in the bird's close-ups the multiple wires (more than six) holding the fake bird are visible. (00:18:40)
Other mistake: When Striker and Turner are fighting on the landing with the bookshelves, Turner's stunt-double is wearing his belt with the belt tip facing his left side, whereas the actor is wearing it the opposite way, with the tip facing his right. (00:37:50)
Deliberate mistake: After Straker shoots Turner, he slumps over in his HS mini car and it goes around in circles. Then, the last shot of Turner is a flipped shot; note Turner's uniform patch and the car's backwards HS. (00:46:05)
Revealing mistake: In this episode the aliens with the help of 'turncoat' Turner have frozen a moment in time in which they will attack and destroy SHADO HQ. Everything and everyone is frozen in place - except for the guy in the background walking across the road during Straker's and Turner's 'car' chase in the 'Harlington/Straker' go carts.
Other mistake: When Paul stands up for the verdict, he's told the date and time for execution, and in his extreme close-ups we can see the hairpiece mesh tape at his sideburn hairline. (00:02:25 - 00:28:10)
Other mistake: The doorway between Straker's office and Miss Ealand's office does not have the "gap" on the floor that separates the rooms, which allows Straker's office to descend. (00:40:50)
Continuity mistake: When Straker and Freeman arrive at Miss Ealand's office, there's a white jacket hanging on the red upright coat rack, but next shot as the doors to Straker's office open, the jacket has vanished. (00:40:55)
Revealing mistake: In the interior shots of Mobile 1's cockpit, we see that there's a crew of 3 and that the pilot is black. But in shots of the exterior (miniature model stock footage), there's only one occupant, a pilot, and it's a doll with distinctively Caucasian features. (00:26:30)
Continuity mistake: A UFO crash lands in Canada and sits amidst trees in a wooded area. Just before the craft explodes, the only snow visible is on mountains in the distant background. After it explodes, however, the ground and trees all around it are suddenly covered with snow. (00:36:30)
Visible crew/equipment: While Russ and Anne are on horseback, Russ pursues the trespasser and threatens him with the rearing horse. When Anne calls out, "Russ," and takes off after him, the boom operator and boom pole/mic are visible at the left side of the screen, just as Anne passes the tree. (00:11:40)
The Responsibility Seat - S1-E25
Visible crew/equipment: When SkyDiver is told to launch Sky One for the search, just as Waterman gets his jacket on, the boom mic pops up into view at the bottom right corner of the screen. (00:17:30)
The Responsibility Seat - S1-E25
Factual error: Moon Base is imperiled by a rogue Russian mining trawler said to be heading "straight for it." But several shots of the vehicle show it veering wildly in very wide arcs, moving far too erratically to determine that it's on a collision course. (00:38:00)
