Episode QuoteEdit

"I go to shape the future of eternity. And I need your help."[2]


After destroying an asteroid on a collision course with the moon, an even larger obstacle appears - an entire planet! On a recon mission, John Koenig encounters an inhabitant who convinces him - on the basis of faith - that the moon and the planet must collide. But no one else supports Koenig's stand.[3]

Errors and Explanations - Internet Movie DatabaseEdit

Plot holesEdit

  1. Alan Carter has difficulty releasing the bomb from the grapple on his Eagle Transporter. But it has been revealed in other episodes that the Eagles can jettison their passenger / service modules. The bomb, attached to the undercarriage of the module, would have then fallen away and the Eagle itself would have been freed. Something could have caused the grapple release to malfunction.
