A nameless member

Visible crew/equipment: When Blue Thunder approaches the chicken shack, you can see an entire camera crew on the roof of the building across the street. (01:31:45)

Revealing mistake: When the van gets flipped over outside the BBQ chicken place, you can see the cannon that flips the van over. (01:32:20)

Continuity mistake: In the climactic chase scene, when Murphy is shot through the window, he is shot in his right arm and there is a hole in the window with blood on it. When he does a 360 degree loop in the helicopter the broken window and blood appears on his left side—the opposite window to that which he was shot through. (01:42:20)

Deliberate mistake: When Cochran sabotages the Jet Ranger helicopter by loosening the nut on the bolt securing the linear actuator governor, the bolt is inserted in the wrong direction. The bolt should have been heads up to prevent it from falling out as it did causing the helicopter to crash. Moreover, the linear actuator is on the opposite of the engine from where Cochran disconnected it. (00:38:05)

Continuity mistake: When Roy Scheider's partner is killed, he is run over by a car. After the car runs him over, his body rolls and you can see his arms swinging freely even though his hands were bound by the plastic ties. Later when you see his body, his hands are bound again. (01:10:30)
