Visible crew/equipment: After the demonstration at the blackboard, the big group of soldiers walk over to the big table with the picture of the world on it. As they walk away from the blackboard, they turn and walk down some steps, and as they do you can see the shadow of a boom mic pole on the upper side of the grey part of the wall. (00:55:40)
Visible crew/equipment: When the martian space ships first appear you can see the wire suspending the models. You can clearly see the wires every time you see a martian or martian space ship.
Visible crew/equipment: When the radio reporter is broadcasting before the first attack, he is speaking into a microphone connected to the radio truck. After the Martians begin shooting, he dives into a small ravine. You can see his microphone cord being manipulated off camera to the right where it is being cut by a crew member.
