Clerk: Do you swear on the Constitution of the United States to tell the truth, the whole truth and nothing but the truth, so help you God?
Jive Man: Ain't no thing.
Defense Attorney: Would you describe, in your own words, what happened that night?
Jive Man: Check it, bleed. Bro was on! Didn't trip. But the folks was freakin', man. Hey, and the pilots were laid to the bones, Homes. So Blood hammered out and jammed jet ship. Tightened that bad sucker inside the runway like a mother. Shit.
Trivia: When the shuttle takes off, a piece of music from Battlestar Galactica is played - specifically the music from the Nova of Magadon sequence in Saga of a Star World. The navigator is played by Kent McCord who played Captain Troy on Galactica 1980.
