During the air battle, the tail rotors of the UH-1's keep changing from facing to the left to facing to the right.
When Airwolf shoots the last BLACK UH-1 down the exploding wreckage is a RED and WHITE Hughes/MD 500.
When the terrorist "shoots" in the theatre, he is standing at the top of the seats which angle down, he points the gun upwards yet the bullets hit the front of the stage which would be below or level with him.
