KANSAS CITY - The third week in September is known as National POW/MIA Recognition Week.
It's a time to honor service members who were prisoners of war and those who are still missing in action.
McConnell Air Force Base in Wichita has been hosting a series of events, including a 24-hour memorial walk that began on Tuesday morning.
While teams worked in shifts, one service member committed to walking for the entire 24 hours as 2-flags continuously moved around a 1-mile section of the base.
National POW/MIA Recognition Day was established in 1979 through a proclamation signed by President Jimmy Carter. Since then, each subsequent president has issued an annual proclamation commemorating the third Friday in September as National POW/MIA Recognition Day.
Other events at the base include a wreath laying ceremony, and a closing tribute.
The government says there are approximately 81,000 American service members and civilians unaccounted for from past conflicts, with the majority lost during World War II.
