ST. PAUL, Minn. — On the order of Governor Tim Walz, flags at state government facilities will be at half-staff to honor those who died in the 9/11 2001 aerial attacks on New York City and on the Pentagon and also in the crash of a third plane en route for an attack on either the White House or the Capitol. Some 2,977 people died, not counting 19 terrorists who highjacked the planes.
