 CONT: In "Instrument of Distruction, Part One" When Captain Scarlet  is in the engineering room he knocks out the engineer but in later  shots the engineer isnt anywhere in the room. The same thing  happens again in later in the episode when Captain Scarlet knocks  out a security guard after escaping from his cell but a few seconds  later, when Captain Blue runs past the same area, the unconscious  security guard is nowhere to be seen.
