Visible crew/equipment: When Wonder Woman arrives at the Diamond H ranch and is introduced to Charlie, just as she kneels down in front of the young boy, the shadow of the boom mic is moving at the top left corner of the screen (widescreen version).
Visible crew/equipment: When Wonder Woman arrives at the Diamond H ranch, the housekeeper opens the front door and the reflection of lighting/equipment is visible on the glass. Additionally, there's a prominent flagpole at the front of the house with the Flag of Texas flying high, but the problem is it's being flown upside-down with the red stripe at the top, when it should be the white stripe at the top. Proud Texan JP Hadley would know better.
Visible crew/equipment: While JP checks the kids before their breakfast he tells them they could all use more elbow grease behind their ears, and as the camera pulls back the shadow of the boom mic is moving on the wall, at the right side of the screen (widescreen version).

Factual error: Wonder Woman is flying to Hollywood, and the iconic sign is shown. However, in the early 1940's (when this season is set), the sign read 'Hollywoodland'.
The Return of Wonder Woman - S2-E1
Factual error: When Steve gets attacked by the bad guys and Wonder Woman shows up, the lady in the car pulls out a camera and films the event. She sits still, the car isn't moving, and she does all the filming from the same position. However when she watches the playback, the film shows footage from multiple angles and varying distances, which is impossible because she and the camera were in the same spot the whole time.

Continuity mistake: Steve complains that he can't steer the Jeep. The Japanese doctor is using mind control to keep Steve from being able to control the Jeep. However, in several shots, Steve can easily be seen steering the Jeep despite the doctor's continued control over it.
The Bermuda Triangle Crisis - S2-E4
Revealing mistake: When Wonder Woman drops a mine into the water, she's supposed to be dropping it into the ocean. However, you can see a drain plug of some sort in the background and the "ocean" is obviously a pool, or similar.
