Blade Runner / FAQ / Leon's Interrogation
The 110-story New York World Trade Center that made headlines when it was
bombed in February 1993 had about 100,000 people inside at the time.
According to various articles, the Tyrell pyramid is 6-7 times taller
(700-stories). Since the top of the pyramid is apparently several times
larger than the footprint of the WTC, the base must be enormously larger.
Plus, it is surrounded by four buttresses, each of which must be greater
in volume than the WTC. From this we can speculate Tyrell's pyramid must
be larger than the WTC by a factor of 100 or more and house 10 million
people. It should be easy to get lost in a crowd that size. Add in the
fact there may be other people that look like Leon and you've got an
impossible job. We also know that the Tyrell Corp. security is not
perfect because Bryant tells Deckard one got fried trying to break in
and the others got away, and Batty gets in and kills Tyrell.
