it would have been quite a bit easier to design a pod with no weakest point if it had no entry hatches , but then that would have required us to make the pod with me in it from the start ; the engineers did n't want to cast the mold of the pod with me inside it because the interior surface needed to be designed and developed in a special way so as to deter deformation that would result from the exertion of my relativistic body upon the material .
