A U.S. Army training exercise in Port Huron left a historic building damaged when "rotor wash," high winds created by a helicopter's rotor, caused bricks to become dislodged and fall to the ground, The Times-Herald in Port Huron reports.  Before hitting the ground, however, the falling debris struck an awning on the building, destroying it, which then led to some of the buildings windows being blown out, according to the report.

Military training has been happening throughout southeastern Michigan, with exercises in and around Flint last week and over the weekend.

Training is expected to continue through June 12th.  A U.S. Army spokeswoman says no further training will happen in Port Huron but can't say what other cities will play host.
