Visible crew/equipment: When Dr. Irina Spalko is descending the cliff, you can briefly see the harness cable that is holding her up right next to the rope on which she is climbing down.
Visible crew/equipment: During the jungle chase, Marion jumps out of the truck, leaving Dovchenko driverless. A few shots later, Spalko fires on the two amphibious vehicles, and when Mac removes his cap to check his head, the actor's modern wired device (earbud or mic perhaps) drops out from under his scarf/shirt and hangs over his shirt. Later, in the chamber with the crystal skeletons, Mac admits to lying about the CIA, then as Spalko climbs the chamber stairs, it looks like her lav mic is a bit visible between two upper buttons.

Visible crew/equipment: As they are running away from the ants, you can see a rig of stage lights under the jeep Col. Spalko's crew was driving.
Visible crew/equipment: After everyone has fallen into the water beneath the obelisk and the skull has been retrieved, Indiana is leading everyone out of the water and a prop light can be seen on the big rock spike behind Mutt. (01:40:25)
Visible crew/equipment: Indy is at the nuclear test site and exits the house and comes out front. He knocks over the boy on the bike and air raid siren goes off. Just as he stands upright, in the window with curtains, you can see a reflection of a crew member walking by.
