What was that situation on the news today about that guy hacking into the pentagon?

what did he find out and how did he do it? would it not be more interesting to hack into area 51? or area 52? is it area 51 or 52 , i get confused? never mind hacking, its not a good thing, too complex and anyway, i have enough trouble accessing never mind anything else. all above my head but just caught the headlines, he was 19 or sumet. what do you computer geeks know about this case?
