Good thinking George as the ship must have some sort of ducting that maybe one of the smaller members of the team could be able to gain access to the bridge by crawling inside it.
The fire is a option but it would have to be very controlled by us.
Looks at everyone trying to break into the bridge and simply says,
"Alright, so can we go open the cargo now?"
Out of Character:: The fire does not seem to be an option based on what I read. Makes sense anyway because you don't put a ship like this in space with things that can cause a fire. We should look at the cargo again. Maybe we can get some records on who its supposed to go to?
I say that with all of us being trapped there with nothing to do then I would expect that the boredom would work on us and we would/ could not help but to look and see what the cargo was.
My vote is that we try to find out what we are carrying.
Out of Character: You know we could speed this along if we do that and everything else we like need to get passed what this ship is about.
Out of Character:: Alright so like who is our second leader in this again or do I just post because its been awhile now and I don't want my character to like die from some unknown disease or something because we're late with our actions.
