User blog comment:Skyzy/10 Things the Mountain Men did wrong (besides not realize Lovejoy hadn't reported for duty in a few days)/@comment-26525483-20150706031645

Mount Weather was weak on the inside because it was stong on the outside. Everything from the chemical room to the where they farm the food, to the control room need to be simple to pass onto the next generation. now days if something is very complex like the LHC they spend months looking for the right employees with the right training. and what if a few or all the engineers die before the new generation is properly trained? thats why it has to be simple enough to pick up.

before the nuclear war there were probably a few dominate providors of operating systems, then after engineers of the Ark had 100 to learn how to crack them.

with regard to #6 they didnt even want to donate blood, why would they donate marrow? the kids already felt threated by knowing what they did to the grounders, they were ready to bolt. remember Harper ( i think ) went missing while they were breaking in to Dante's office. so they ( Cage and Dr. Tsing ) knew they were starting to get anxious.
