Continuity mistake: Blake commandeers the kidnappers' motor home, gets behind the wheel and has to push aside a curtain obscuring the windshield. Then the camera view switches to an exterior shot of the RV driving away - and the curtain, which should still be bunched in the window corner as it was in the interior shot, has vanished altogether.

Revealing mistake: The "remote control" model plane lands and sneaks through some bushes to spy on Blake. You can see the filament line pulling it. And the picture it sends the bad guys with its mini-camera not only zooms in (unlikely technology in 1973), it also delivers an unobstructed view when the plane is sitting in foliage that should block part of the shot.
