Visible crew/equipment: When Cooper steps into his car, just before the flat tyre, the boom of a microphone is visible in the reflection of the rear window. Also, the top of head of the boom operator is seconds later and remains visible for quite some time. (00:04:57)
Visible crew/equipment: Murph sneaks into Cooper's truck to get to NASA. Once Cooper closes the vehicle door after placing some blankets into it, a boom mic can be seen in the left wing mirror. (00:22:05)
Visible crew/equipment: When Cooper gets on board his pickup with the kids to follow the drone at the beginning of the movie, at the precise moment when Cooper is getting on board a boom microphone is reflected on the door's window moving synchronously with the actor's movement.
Answer: Cooper would have already met his other family members (grandchildren and great-grandchildren) when they first arrived at the space station and before going in to see the frail Murph, who made the trip while in-stasis. Because she is so frail, everyone would discuss beforehand how the meeting should proceed. Also, it is already a long-running movie, and adding an extended "meet and greet" scene would drag out the ending and lessen the emotional reunion between Cooper and Murph.
