OMAHA, Neb. (AP) — The governors of Nebraska and Iowa have ordered flags flown at half-staff in memory of the late astronaut-hero John Glenn. Nebraska Gov. Pete Ricketts and Iowa Gov. Terry Branstad on Friday ordered U.S. and state flags be flown at half-staff from sunrise to sunset the day of Glenn’s burial. The orders were in keeping with President Barack Obama’s proclamation issued in the wake of Glenn’s death on Thursday at the age of 95.

Glenn was the first American to orbit the Earth in 1962, and was the oldest man in space, at age 77 in 1998. A U.S. Marine and combat pilot, he also served as a Democratic U.S. senator, representing Ohio, for more than two decades.
