Operation Exodus Strongly Considered or Initiated

Intro

Year One

• "Breakaway": Considered, with Main Computer being ordered to compute it, but too many new factors and changing factors leave Computer unable and insisting "Human Decision Required." The decision is to stay with the Moon rather than risk the likely impossible return.
• MOLAD: Early stages are started, but the operation is cancelled before actual evacuation commences.
• ATAP: there are actually two cases presented in this episode.
• "Guardian of Piri": The Guardian, already influencing most Alphans, instructs an initiation of Operation Exodus, and subsequently, through Main Computer, controls the details. Operation Exodus is completed, shoddily. On Piri, there is no attempt to take equipment off the Eagles and start a settlement, for that has little to do with the Peace of Piri (the people are in an almost catatonic, drug-like stupor). Once the Guardian is destroyed, the Eagles hastily leave, thus reversing Exodus.
• "Collision Course": Atheria is so large that the Alphans wonder if they might survive the collision if they are on the far side of the planet. The "Operation Exodus" name itself is not mentioned.
• DOD?
• "War Games": After a battle which is disastrous for Alpha, the survivors complete the evacuation of Alpha, for the planet, but are turned back when it is clear settlement is not possible. Then the entire episode is reset: most of the episode was days-in-a-moment warning scenario presented by aliens. Thus, the evacuation never really happened.
• TOA: Initiated but soon aborted?

Year Two

• "Journey to Where" (arguable): Earth of 2120 makes contact with Alpha, tries to set up a means of evacuating the Alphans to Earth, but only three make it there (and in the wrong century), and they can only be returned back to Alpha before contact ceases. However, this would not have been a full Operation Exodus, as presumably only the people and perhaps some computer/paper records and some personal effects would have been taken, not all the supplies needed to survive in space or a new planet.
• "AB Chrysalis"?
• BOW (arguable): Apparent Earth people come to Alpha, indicating they can evacuate the Alphans to Earth, and three Alphans even appear to make it to Earth. However, the Terrans turn out to be aliens masquerading as Alphans' friends/relatives, prompting the Alphans into actions that will destroy the Alphans. The plan is unraveled. No Alphans actually make it to Earth. However, even if it had been real and not an alien deception, it would have been more like JTW, an external rescue mission of the Alphans.
• "The Seance Spectre": Eagles become lifeboats, including major equipment, in case diversion around Tora fails to occur (or presumably due to the possibility of Alpha taking severe damage). Helena worries about this option and people being "at each others' throats" if it happens, but John compares it to words said after Breakaway.

Year Three

• MFMBA: Operation Exodus to Terra Alpha is nearly complete, Sandra completing a message to be transmitted towards Earth, while Alan waits for her in an Eagle, to be the last to leave Alpha.

NOT

• "The Metamorph": Implied by orders given by (an under-pressure) Koenig, during which the first officer protests the abruptness, allowing Koenig to add Directive Four, a clear (to Tony only) contradiction of evacuation. No steps are taken to follow Koenig's false order.
