Omar Abdel- Baqui Detroit Free Press Published 5:38 PM EDT Sep 11, 2019 An American flag soared from Mackinac Bridge on Tuesday morning in the cloudy skies where the peninsulas meet, honoring those who lost their lives in the Sept. 11, 2001, terrorist attacks. It was one of several public displays of remembrance and mourning as people across Michigan and the world marked the attacks’ 18th anniversary. The flag measured 30 by 60 feet, according to the Mackinac Bridge Authority. In Detroit, the city’s police and fire departments hosted a procession that rolled through downtown and a memorial service in Campus Martius. At Michigan State University, the MSU rock was painted white and covered with a painted American flag. Under the flag were the words: “9/11 NEVER FORGET.” More on Freep.com: Bloomfield church cancels anti-Muslim 9/11 event after backlash Moment of silence, tolling bells and Trump mark 18th anniversary of 9/11 terror attack Staff writer Ann Zaniewski contributed to this report.
