Transformers 4 Final Day in Chicago Goes Out With a Boom

As promised, the final day of Transformers: Age of Extinction in Chicago went out with a large boom. Not "the mother of all bombs", but still a big boom that will look great once its slowed down and edited together. The set, not opened to the public, was the South Damen Avenue abandoned silo that was dressed as an unknown Chinese location. As the great images and video thanks to Colin Hinkle show, the site was dressed with China related items, silo itself was rigged with pyrotechnics, and the action was filmed from the air with a helicopter. His video was also used in local news report about the filming.

The second set of pictures near the site are from cmraseye that provides another angle on the explosion. He wrote, "The blast was concentrated at the front of the corrugated out building. Lots of debris blown into the air, bamboo sticks, 55 gal drums ...all kinds of things in the air, will probably look cool on film. ...you can see the pyro/dust bags ignited, blowing out the dust, and several barrels being launched into the air. Contrary to the captions on the Tribune photos online, there were no cameras mounted in the baskets of those lifts. It appears the lifts were cabled to support the frame of the outbuilding to keep it from collapsing on itself when they blew the roof panels off." You can find Chicago Tribune's pics of the boom here. Thanks Jeffrey Marshall for the link.
