The flames were so hot that we could feel it on our faces over 300 feet away as we stood near the corner of Delaware and Whitehall avenues. At first we gawked at the burning factory from about 100 feet away, but a large explosion caused us all to turn and run. But not too far. While watching from some 200 feet away, the police came by and pushed us back to the 300 foot mark just before several explosions in a row came along. The stuff that came down on us out of the sky was cooled enough to not burn, and some of the bits were recognizable as small fragments of colored billiard balls.
