Did anyone who has seen the movie notices the bottles standing upright in the rescue shuttle after it crashed?
The entire mobiliar was destroyed... Except for a dizen bottles standing around^^
Another thing funny thing were their vehicules.
They used some with tires... Seriously? You're flying no-one-knows how far and expect that thete were one will end up, one will find roads?
There was no reason why they shouldn't have used some kind of anti-gravity engine, they seemed to have the technoligy, as they had little scanner probes flying around
