It may be a coincidence, but this is the third time that someone has tried, (in this case, succeeding) to kill David Palmer between 7.00 AM and 8.00 AM. In Season 1, the first assassination attempt was just before 8:00 AM, by the fake Martin Belkin. At approximately the same time, Mandy tried to kill him in Season 2 with a biological weapon. Finally, in this episode, albeit nearly an hour earlier, Palmer is killed in the same hour. (edit) Jon Cassar won an Emmy Award in 2006 for 'Best Director of a Single Episode' for his work on this episode. David Latham also won an Emmy for 'Best Editing For a Single Episode'. (edit) Kiefer Sutherland submitted this episode to voters for Emmy consideration. Subsequently, he won the Emmy for 'Best Lead Actor in a Drama Series' at the 58th annual Emmy Awards in 2006. (edit) Throughout Season 5, Jean Smart receives the "and" credit. (edit) Prior to airing the season premiere, the show "released" Jack's cell phone number 888-9-24-JACK as a promotional tool. (edit)

Haas: That's all I know. Now take me to a hospital.
Jack: Yeah.
(shoots him dead) (edit) Edgar: Spencer, have you talked to Chloe this morning?
Spencer: No, why?
Edgar: She left her apartment about a half hour ago, she should have been here by now.
Spencer: Probably traffic.
Edgar: She commutes against traffic, and she's not answering her cell phone.
Spencer: I wouldn't worry about it.
Edgar: She sounded strange when I talked to her.
Spencer: She always sounds strange. (edit) Cummings: Was she all right?
Logan: No, Walt, she's not all right. She's having another one of her delusions. (edit) Martha: Well Charles, you shut him out of this White House about 18 months ago. He had no real access.
Logan: Except you.
Martha: You don't believe me.
Logan: I didn't say that.
Martha: You didn't need to.
Logan: Martha--
Martha: I am not making this up. I am not crazy. I am not a fool, Charles! (edit) Chloe: How did they find me?
Jack: I don't think they ever lost you. (edit)

When Tony runs out to find Michelle after the explosion, he finds her in the lawn with the door, and some of the grass is on fire. After he tosses the door aside to get to Michelle, the next shot goes wide and the fire is out. (edit) At the end of the episode, when the man who killed Palmer looks for Chloe and Derek in the refinery, we can see a shot where Derek gets his hair out of his face and two cuts later we see the exact same scene again. (edit) If Tony and Michelle gave Jack a new identity to "get across the border" at the end of Day 4, why is he working an oil rig in southern California? (edit) Real Time error: It takes about 50 seconds real time between Jack and Derek getting into the helicopter and them flying through the air in the next scene, however later when Jack, Chloe and Derek try to escape in the helicopter, they wait 40 seconds after entering the chopper before getting out because it is taking too long to power up. Surely 40 seconds would have been enough based on the previous scene.

Edit: A deleted scene on the Season 5 DVD clears up this error, where Jack calls Diane while waiting for the helicopter to power up. (edit) Shouldn't the Secret Service in the room have kept Palmer away from the window since it wasn't as bulletproof as the windows in the White House? (edit)

Jack's girlfriend's name is Diane Huxley. One of John Mellencamp's more famous songs is Jack & Diane. (edit) Jack's Alias
Jack's alias of Frank Flynn was given in honor of author, Vince Flynn. Flynn was brought in before the show's fifth season to help create story ideas. He was brought in several times after the season began production to help wrap up certain story arcs. (edit)
