The WTCs existed for 33-years, from 1968-2001, but were only open for 28-years, from 1973-2001.
Do you recall the September 11, 2001 example connecting all of these numbers? The construction firm that build the World Trade Centers has gematria of '156'; the buildings existed for 33-years, and they came down on 9/11. You can read about that company below.
George W. Bush graduated from Yale, Skull and Bones, in 1968. That is the same year 9-1-1 was made the national emergency dialing code and WTC construction began, August 1968. 33-years later he would become President and 9/11/2001 would happen, with the WTCs collapsing.
7/6/1946 = 7+6+1+9+4+6 = 33 (False Flag) (Bonesmen) (Secrecy) (Masonry)
