THANK YOU!!! This is what I've been thinking all along.
If it's a one-way trip how can they possibly know that the people going back aren't going out in a lava-filled world???
How do they even know they are going BACK in time?
What they should have done was to show the original crew and how they built what they did.....the story line so far has many unexplained questions which MAY be explained later...but I highly doubt it.
It is so far, for me, a tad of a dissapointment.
I'll give it a few more episodes before I decide to ditch it.
