The runway at Hunter Army Airfield, stretching 11,375 feet, has served over the decades — in times of peace and in times of war — as the takeoff and landing place for America’s defenders. On June 21, the 5K/10K Flightline “Dirty Up” Run event will give military and civilians alike an opportunity to walk or run on the expansive runway, get an up close look at military aircraft on display, and hang out with those who fly and maintain the aircraft. “The whole reason for this base is for that runway,” said Lt. Col. Will Bowman, Garrison Commander at Hunter.
