Free for All - S1-E4
Continuity mistake: Throughout the episode, Number 6's lapels switch from having solid to broken white piping and back again.
Character mistake: The second Mrs. Loomis describes Mr. Loomis as having brown eyes to Friday and Gannon. Later when they are interrogating Loomis, a close-up on his face show his eyes are blue.
Factual error: The chopper's main rotors are at a speed enough to cause rotor wash, but the men's coats or hair don't move at all, when they should have been buffeted around.
