Independence Day (1996)

Continuity mistake: David calls Connie at the White House and she walks toward the divided pane windows, then pulls one curtain to the side. In the exterior shot facing her, the pane's white grille is between the two sides of the curtain, but in the next interior shot looking out, there's only clear glass, though we should see the grille, just as we see both sides of the curtain with her hand holding the right side. Then, in the next exterior shot facing her, it's back to the original with the visible white grille. (00:38:25)

President Whitmore: Good morning. In less than an hour, aircraft from here will join others from around the world. And you will be launching the largest aerial battle in the history of mankind. Mankind, that word should have new meaning to all of us. We cannot be consumed by our petty differences anymore. Perhaps it is fate that today is the fourth of July, and we will once again be fighting for our freedom. But not for freedom from tyrrany or oppression or persecution. We're fighting for our right to live, to exist. And should we win the day, the Fourth of July will no longer be known as an American holiday, but as the day when the world stood up and declared in one voice that we will not go quietly into the night! We will not vanish without a fight! We're going to live on! We're going to survive! Today we celebrate our Independence Day!

Trivia: In Area 51 there is a large screen displaying the results of the nuclear strikes against the alien ships. Look under the screen and there is some text in green. Pause it to read the following: "The purpose of these green lines is to lead you to believe that these words mean something", and "And can I see with eye serene the very pulse of the machine Wordsworth".

Question: In the scene where the pilots are receiving their initial briefing, the officer in charge is a Lt Colonel, but in a later scene where the alien ship is approaching area 51, he is a captain. Is this the same officer or is this a mistake?
