While in their rush to grab pictures from this site of this weekend's filming at the Damen Avenue abandoned silo without giving proper credit to Colin H, TFormers did manage to find a great video (below) of the explosives going off on top of the silo that destroyed the bridge joining the two sections. The boom was big enough to set off car alarms that were not exactly close to the site. In addition, TFW2005 used my link to cmarseye's TF4 gallery to catch something I didn't (dang it) - two pictures of two unknown Transformer robots from the first day of filming in Chicago on August 24th. The first is probably Bay approving something from ILM on his Macbook while the other was on the clapper (which is held upside down for some reason).

Update: Pictures pulled at the demand of Paramount Pictures
