Cook's Tour - S1-E4
Visible crew/equipment: At the construction site, when Johnny and Roy climb the tower mast, they stop on the blue platform with the crane operator's cab before continuing up to the main jib. When Roy, Johnny, and the man they rescue walk back across the jib the man slips, and there are a few shots showing the underside of the blue platform, and we can see people moving around on that platform overhead. There should only be four people on the tower crane: Roy, Johnny, the man they rescue, and the officer holding the bullhorn, who's standing at the other end of the jib, by the mast. Nobody is supposed to be on that platform.

Visible crew/equipment: At the construction site, when Roy and Johnny walk across the tower crane's main jib, there's a shot of the entire top of the crane, and we can see the cameraman at the tower peak, who is shooting the footage of the stunt guys from the overhead angle. He wasn't in the previous long shot of the crane. This does not refer to the officer who is standing on the main jib.
