Took this in Friday (10/30/15). I arrived shortly after the 3-11 was pulled. Fire was involving several stores in the cockloft area and rapidly spreading to other occupancies at 3536 W. Irving park Road in Chicago. The overhead view I supplied gives an idea of the construction and layout. Three tower ladders, a Snorkel, and several multiversals and handlines were utilized. Collapse became a significant concern as the operations progressed.
