THIS IS MUCH BIGGER THAN WE KNOW! Of the 176 passengers killed...112 were 'QUICKLY' returning too Canada...Of the 112 returning to Canada, 57 held Canadian  Passports! NOTE: Most were in the Academic community with PHD's = Scientist. TRAINED AND EDUCATED IN CANADIAN UNIVERSITIES! Most of these passengers worked on the  "Black Sites" under guidance of the CIA! Canada was used as a covert location to train  and educate them and too hide there activites.  THEY WERE BUILDING THE NUCLEAR SITES! (The dead tell no tales)
