The trio reached the middle airlock without issue and, after a couple of minutes of examination, Reva was able to locate a small service panel.  A bit of fancy engineering work later and a patched together power connection, and she was able to get the airlock's local redundant firmware to at least attempt to boot-up.  Unfortunately it wouldn't do much else.  It would load up to where it should have activated the full software, but instead crashed and restarted upon doing so.  It continued to do this, over and over, booting and crashing in a cycle that took a few seconds each time.<br/><br/>There was information to be gleaned though, the firmware did run through a list of checks.  It didn't have a connection to the central computer, its outer and inner doors were sealed, and current atmosphere levels were 0 for a whole list of molecules.  That probably meant within the airlock itself, but it wasn't explicitly stated.<br/><br/>The more Reva examined the system the more she was convinced that she could get it to work on battery power.  The only issue was that it would take time, half an hour to an hour most likely.
