Thank you TEXCOLO, just like you said. After a research I have found some informations about engineering questions, but nothing about interior! observatory, suite of Mr. Chrysler... is incredible, an important piece of American history, an icon of new york, nobody catched a photo of interior of the spire?! (really just one of the aobservatory very old in wich it can see just a saturn shaped lamp). I will be a provincial but americans are very strange...
Anyway there is something now very strange... Is this true???
