 PLOT: When Ellie is first traveling through a wormhole in the pod,  the chair is shaken completely free of its connection to the  ceiling, then floats freely once its loose. Yet this is never  mentioned again. Ellie is shown to be left with no evidence of her  adventure, except for the 18 hours of static recorded by her headset  camera, but what of the broken chair that she was mysteriously no  longer strapped to?
