Regarding the pod that returned Julia and the other hyper-sleeping astronauts to Earth.
Why had Jack not noticed suspended animation capsules with the names of himself and Vicka?
Surely they were not expected to stay out of suspended animation for the majority of the journey to Titan. He was in a rush the first visit (especially after finding Julia), but you'd think he would have taken more time to look around when they returned for the black box. Or of course Julia might just have pointed it out with an "I'll explain later".
Speaking of the 2nd visit, why had the Tet not immediately sent drones to reduce the pod to rubble1 after the first visit, in order to destroy all the evidence that might make Jack even more suspicious than he already was?
It remarked when he visited it that he had been disobeying orders for some time - so it had its suspicions of him.
- Or at least 'more drones' after Jack destroyed the one that had killed most occupants, and was about to kill Julia.
In lieu of a sourced answer, I will give the tick to the most plausible answer presented.
