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 Thomas Whitmore: I don't understand, where does all this come from? How do you get funding for something like this?
Julius Levinson: You don't actually think they spend $20,000 on a hammer, $30,000 on a toilet seat do you?

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?
