That's what they claim. Pretty sure it's just a convenient lie that the engineers tell everyone to keep morale up. That's the only explanation I can see for the officers always barely "making it out" of every single underdog scenario they jump into.
They've died dozens of times, but keep getting printed out and told they made it because they're special.
Could be there's too much data to store, so it's just read once, transmitted, part of it is kept in a buffer in case retransmission is necessary, and then discarded.
