In this ex­cerpt from NBC's "9/11 -​ 5 Years Lat­er -​ Hangar 17," pre­sen­ter Bri­an Williams in­tro­duces us to "all of the wreck­age that was tak­en Ground Ze­ro, all of it sa­cred." He in­forms us that it is "all await­ing a home, a per­ma­nent memo­ri­al...all be­ing cared for in a hangar at JFK's Kennedy Air­port." Williams notes "a room with a form that's dif­fi­cult to de­scribe. In any oth­er mu­se­um, it could be passed off as a me­te­orite. And, while this was born of in­tense heat, this is al­to­geth­er dif­fer­ent. This for­ma­tion is re­al­ly four sep­a­rate sto­ries of the WTC: com­pressed, com­pact­ed, in­cin­er­at­ed, ex­posed to tem­per­a­tures as hot as the in­ner-​earth. On it, you can see the type-​face from print­er pa­per which was ex­posed to so much heat, it car­bonized." For those that aren't aware, the in­ner part of the earth is re­ferred to as the core. The tem­per­a­ture of the out­er-​core of the Earth is es­ti­mat­ed to be some­where be­tween 7200-​9032ºF, while the in­ner-​core is es­ti­mat­ed at some­where be­tween 9032 -​ 10832ºF. Williams con­cludes his re­port by stat­ing, "all of that ma­te­ri­al -​ a hangar full of ma­te­ri­al -​ still rep­re­sents less than 1% of the wreck­age tak­en here from Ground Ze­ro." The oth­er 99% of the ru­ins of World Trade Cen­ters 1, 2 and 7 were placed in land­fills, while most of the steel was shipped over­seas to Chi­na to be sold as scrap and re­cy­cled.
