Day 3: 2:00 A.M.-3:00 A.M. - S3-E14
Continuity mistake: Chappelle shows Jack the security footage of him shooting Nina. He shoots her three times. He fires the gun with more of a gap between the gunshots on the footage than he did when we saw him kill her.
Day 3: 1:00 A.M.-2:00 A.M. - S3-E13
Continuity mistake: When Jack leaves the cockpit he puts his gun away in a holster on his back. When he gets back to Nina and Chase he puts his gun away a second time.
Day 3: 7:00 A.M.-8:00 A.M. - S3-E19
Continuity mistake: When Kim is working undercover, dressed up in Saunder's daughter's clothes, she comes out of the Ladies' toilets wearing brown trainers. As she sits down at the library computer, you see she is wearing her very high heeled shoes. A few seconds later, as she is walking between the library shelves, she is wearing brown trainers.
Day 3: 8:00 A.M.-9:00 A.M. - S3-E20
Continuity mistake: When Jane Saunders gets into the car to go to CTU she and Kim have switched clothes again. Though the top worn by Jane is not the same as the one she wore earlier, which Kim then used. It's similar but not identical.

Day 3: 10:00 A.M.-11:00 A.M. - S3-E22
Continuity mistake: During the hostage exchange, there is a shot of the black man waiting for Jane Saunders to walk to him, in the background we can just see a man stood behind a car door. However, in the wider shots and when Saunders jumps out of his car, the man is not there.
Day 3: 6:00 P.M.-7:00 P.M. - S3-E6
Continuity mistake: When Chase calls Chappelle from his car, his mobile shows the date and time "Sep 4. 03 (Thu) 2.15pm" rather than the actual time 06:09, which is displayed seconds later on screen. (00:09:10)
Day 3: 9:00 A.M.-10:00 A.M. - S3-E21
Continuity mistake: When Tony locks down Tech One from his office, the CCTV screen he's watching shows the monitors in there displaying the "locked down" message moments before they actually change to the message in the next shot within Tech One. (00:36:40)
Day 3: 12:00 P.M.-1:00 P.M. - S3-E24
Continuity mistake: In the teachers' lounge Jack tells Chase that the second floor is cleared. When he doesn't get an answer he realises something is wrong and runs down to the floor Chase is searching. After he's cut Chase's hand off he runs out into the hallway and into the lounge which is suddenly on the same floor Chase was on.
Day 3: 4:00 A.M.-5:00 A.M. - S3-E16

Day 3: 11:00 A.M.-12:00 P.M. - S3-E23
Continuity mistake: In the scene where Wayne and Fox are in Sherry's house searching for the pill container, right before Sherry asks, "What's going on here?" Wayne is seen wearing latex gloves. The camera then cuts to Sherry. When it cuts back to Wayne, his gloves have magically disappeared.
Chosen answer: Nobody knew, not even the writers, until at least halfway through the season when they were writing the end. They wanted to keep all options open.
