How long did evil forces in DC plan the 9-11 event and gather cover information for its delivery?

the f-4 phantom jet crash test was rigged ,not that fact would surprise the enlightened but its interesting to know this the f-4 used in the test was just a empty hull or shell,,its fuel cells filled with water and its heavy titanium/stainless steel engines removed from the jet before the show test crash,,,,its two 8,000 pound tf-30 engines where used by the same company in another test on cement structures,,,,,and guess what no one will ever see that one,,,,,,,,see heavy jet engines do not evaporate,,,,a href="http://killtown.blo.com/2008/03/is-sandia-labs-f-4-phantom-rocket-sled.html" rel="nofollow"http://killtown.blo.com/2008/03/is-…/a
