I agree GoGlenroy - let's face it - if building 7 did come down in it's own footprint by the fires on that day we would have to demolish (or strengthen) probably 85% of the world's skyscrapers and other multi story buildings as they would be proved (because of building 7) to be totally unsafe.
Incidentally GoGlenroy, in an earlier post 28/2/ you mentioned "Given the RBA is a foreign corporation" - could you elaborate on that? Much appreciated if you could.
