Major Danton takes off with seven other pilots to stop Kaleel's invasion, so there should be eight Earth starfighters. Kaleel later comments that there are eight; however, whenever the starfighters are shown in formation, there are only six.
When Wilma is kidnapped she departs in a shuttle which is the model used for Princess Ardalla from New Chicago. Over the desert it changes to the Galactica Shuttle model used in the series Battlestar Galactica.
When being placed in the "hot room", Wilma suddenly has a metal headband that she wasn't previously wearing. (Her captors could have put it on her, but there is no reason to believe that they would have, since she could have just taken it off again once placed in the "hot room".)
Heading to the planet Vistula, Buck and Wilma are in a 2-seater ship, escorted by 2 Starfighters. When the reverse angle is shown we see the Cargo Sled being escorted by 2 Starfighters.
The shots from inside the Vistulan ships show that the joysticks are similar to the Earth Starfighter's, with the fire button being on the side. In the exterior shots the fire button is a large red button mounted on top of the joystick.
This episode's title is somewhat misleading, since there are slaves of both sexes and all ages.
Dr. Huer tells Buck and Wilma that they will be leaving at oh-ten-hundred tomorrow. He should have said "at ten-hundred." There is NO "oh" before ten-hundred.
Major Danton informs the pilots that they'll be outnumbered, "nearly ten to one", but the monitor shows fifteen enemy ships and ten earth ships, including Buck and Wilma.
When Buck is pulling Wilma up through the tunnel to escape the hot room, you can see runs on her pantyhose plainly visible on her backside. So, Wilma wears pantyhose which couldn't withstand all that rough treatment. Any girl would tell you that's how it is.
When Buck is entering the cave, automobiles can be heard passing by on the road behind him.
When Buck uses the grenade to launch himself at the overhead pipes his safety wire is visible.
When Wilma shoots one of Kaleel's ships, it's shown to be a Draconian fighter; there are two other scenes in which Draconian fighters are visible, notably when Brigadier Gordon shoots down two and is congratulated by Buck for it. They are clearly stock shots.
Obvious phony beard on Roddy McDowell.
After Buck's fight in plant 347, as he goes to leave, he pulls the door open, but when shown from outside the building, the door opens to the outside instead.
Guest star Roddy McDowall has his last name misspelled in the credits as
"McDowell".
A large fixed wing aircraft, not part of the action ,can be seen briefly in the top right of the frame (DVD index point 2:06) after Buck and Major Danton crashed on the slave planet.
When Buck is propelled up to the pipes after the blast, you can see the wires holding him as he's grabbing them.
Rather than steal one of the armada's ships to fly back to Earth to warn Dr. Huer about the attack, Major Danton could simply have used its lasers to blast all of the remaining ships on the ground.
The prisoners' handcuffs are removed when they are placed in the "hot room". Why would the captors unbind prisoners who are about to die, especially since unbinding them would accomplish nothing more than give them increased mobility and thus greater opportunity to escape?
