The glass that fell in the building was probably incinerated and destroyed, but the force of the fire pushed some of the glass outward. We were able to find, by crawling around and even going through wrecked cars, little pieces of the glass. We probably can account for every color and glass pattern on there. With the pieces of glass, in conjunction with the photographs, we could re-create these windows almost exactly.
