Flight of the Phoenix[edit]

The events of this episode likely occur over several weeks with the construction of the Blackbird, and it was designed to have a vague timeline per the episode podcast. However, In "The Farm," Commander Adama gives Cally Henderson a 30 day sentence on Day 61, the same day he resumes command of the Fleet. It is likely that Henderson's release marks day 91. Precise date stamping is problematic regarding most other events outlined in the episode.

Between Days 91 and 175[edit]

  • Laura Roslin is given a few weeks, a month at the most to live.
  • Traces of the Cylon virus (TRS: "Valley of Darkness") reemerge as a logic bomb and begin to disable Galactica's systems
  • Tyrol begins construction of the Blackbird
  • Galactica routs hundreds of Cylon fighters
  • Cylon logic bomb purged from Galactica
  • The Laura, the completed Blackbird, is successfully tested


The events in this episode create a timeline problem in season 2 events. As such, most events here are not timestamped as there is no information to discern a date.

  • Admiral Helena Cain assumes fleet command
  • Day ~175:
    • Tyrol accidentally kills Pegasus Lieutenant Thorne and is arrested together with Helo

The originally aired episode contained an error in the form of a second time stamp title card which said "ten weeks ago" referring to Boomer's death and resurrection, which placed the events of the previous episode, "Resistance," ten weeks prior. This was corrected to "ten weeks later" for the DVD release and subsequent airings, dating Boomer's death ten weeks after "Zero Hour," the attack on the Colonies. However, even this date may be incorrect, as Boomer is killed on approximately day 53, which is just over 7.5 weeks from Zero Hour, not ten. While these inconsistencies within the episode makes the time of events problematic, given what is established before with the downloading process and even taking into account the flawed dates, Caprica-Six and Boomer are resurrected well before the birth of Hera Agathon.

  • Day 1 (flashback):
  • Day 53 (flashback): Cally Henderson kills Sharon "Boomer" Valerii (TRS: "Resistance")
  • Precise dates unknown: [4] [5]
    • Boomer is resurrected
    • A Number Three "D'anna Biers" unit tasks Caprica-Six to help Boomer adjust to her Cylon nature.
    • Caprica-Six and Boomer resolve to persuade the Cylons to adopt a new approach in dealing with the Colonials.
  • Day 270:
    • Hera Agathon born, approximately one month premature [6]
    • President Roslin, in secret from Admiral Adama, has Hera's death faked and the child hidden as an adoption by Maya.

Season 3[edit]

  1. The episodes "Resurrection Ship, Part I" and "Epiphanies" state that events in the episode "Pegasus" and the episodes immediately following it take place six months after the Cylon Attack. Ron D. Moore states in his podcast that it took Tyrol "weeks" to construct the Blackbird and a large amount of time passes in this episode as a result. While this figure was assumed to be 2 to 4 weeks, the only plausible way that "Pegasus" and "Resurrection Ship, Part I" can take place six months after the attack is if "Flight of the Phoenix" actually lasted three months from beginning to end. Roslin was told in this episode that her cancer had accelerated, and she had only one month to live. As Cally Henderson's "welcome back" party happened earlier in the episode, when she was released from the brig around Day 86, a considerable period of time (several weeks at least) pass between these two scenes
  2. This probably takes place shortly after him taking command of the battlestar, and possibly some time before the main events of "Razor".
  3. See Razor#Analysis for the dating of this episode.
  4. 4.0 4.1 As alluded to by Caprica-Sharon in "Scattered" after Kara Thrace kills a Number Six in the fight in the Delphi Museum of the Colonies on Caprica. She relates that the dead Six is downloading right now and probably reporting their position: "Her consciousness is being downloaded into another body right now. And when she wakes up, she'll tell them exactly where we are." From this it can be inferred that the process from death to resurrection is very short, usually measured in minutes if the transmission can be picked up immediately; and hours at most if there are mass deaths, such as the parking garage explosion in "Downloaded" after Caprica-Six kills the Number Three: "Boomer: How long till she downloads and tells them what happened? - Caprica-Six: We had a lot of people in the cafe. At least 36 hours till they get to her. Long enough." These facts considered, it is a virtual certainty that Caprica-Six resurrects on the same day of the attack.
    • Number Three's comment regarding Starbuck that "She was o­n Caprica a couple of weeks ago. She escaped with the help of another Sharon." could be one placement of the events in the parking garage a couple of weeks after Starbuck's escape from Caprica on day 62, placing the parking garage scenes, if it could be assumed that a "couple of weeks" to be two weeks, to be roughly at day 75 and contemporary with "Final Cut".
    • Another comment by Number Three also provides a time frame. As they sit in the café on Caprica, just before the explosion, Caprica-Six states (falsely) that Boomer asked her to help her move out of her apartment. Three responds: "You know what? Which is what we've been asking her for weeks." "Weeks" could be from two to four weeks. However, at four weeks or more than that, it would be most likely be couched in the term of a month. Boomer likely went home to her apartment after being resurrected to be somewhere familiar. This time frame fits with Three's comment of Starbuck escaping a couple of weeks prior. Assuming that Boomer is also resurrected very soon after her death, approximately three weeks earlier, this also makes the scenes roughly contemporary with "Final Cut".
    • Alternatively, one could consider Number Three's comments writing errors, but that would require a delay of about 2.5 weeks between Boomer's death and her resurrection. One possibility for that would be the time it takes a pursuing Resurrection Ship to pick up her consciousness.
  5. The date of Valerii and Agathon's child is speculated from the events in Season 1 and during the events of "Resurrection Ship, Part I," assuming that the humanoid Cylons share the same gestation period that humans do, and that the birth of their hybrid daughter is not premature. It is later confirmed that Hera's birth occurs on Day 270.
  6. While the time needed to get to Caprica may be considerable, the amount of fuel, rations and supplies would make it unlikely that the trip takes more than one-half day.
