After Goose is killed Maverick is assigned Sundown as his navigator, on their first sortie Maverick will not fire because, "It doesn't look good" after landing, and as they climb out of the aircraft, the name 'Sundown' can be seen across the front of the navigators helmet, seconds later as the pair walk towards the camera the name is no longer there. This is the scene where Maverick grabs the rio and says "I will fire when I am god damn ready" or words to that effect. Surely someone should have picked up on this one.
