Visible crew/equipment: At the end of the film, when the news about the train and helicopter accident plays on the TV, as the camera pulls out, the camera's reflection is visible in the blue window shutter. (01:44:08)
Visible crew/equipment: When Ethan is going down to the security room on a rope you can see a man standing on the floor at the bottom. It's right after he starts to descend.
Suggested correction: What Sacha said is correct, but if this is referring to the second time Ethan descends into the room, then... that's obviously the employee that entered the room, not a crew member.
