This from reader Eric Haak:
Still & Box Alarm @ 47th and Knox on June 27th. Engine 34 pulled up just before 1:45 pm to the Right Away Pallet Company and within 2 minutes called for the box. The area involved was a 125 x 125 storage lot stacked tight with 10-foot tall columns of pallets. Engine 34 fed Tower Ladder 54 inside the company’s yard while Truck 52 pulled into a lot to the west of the involved area and was fed by Engine 123. Tower Ladder 39 set up in the empty parking lot to the south of the pallet yard and was fed by Engine 32. A total of 5 lines were used to bring the blaze under control and 2-2-5 struck out the box @ 2:38.
Hank Sajovic also went to the scene and submitted a few images.
