The North Vietnamese Army didn’t give up easily, and they continued pressing attacks against not just ground forces but against the air bases as well. In early March, they tried to attack Tuy Hoa and the Military Assistance Command in Vietnam (MACV) about five miles to the north, but the artillery shells fell short and caused only some anxious moments and frayed nerves. However, the next night as Arnold sat on alert, some Viet Cong worked their way into a village about two miles from the end of the runway at Tuy Hoa and the shootout resulted in a spectacular display of firepower that lit up the night sky and easily topped any fireworks show with all the tracers, smoke, explosions, and shrapnel flying around.
The Emerald Knights flew both the F-100D model and the two-seat F-100F model. Although the F-100F was used primarily for training, it was also used for combat on occasion. Since there were a limited number of pilots, the squadron schedulers would normally put one pilot in the F-100F when it was scheduled for a combat mission, and a non-pilot officer would often fly in the backseat to act as an observer. As observers, they helped spot targets and anti-aircraft artillery. It was good experience for the lawyers, supply officers, and other non-pilots and they could even receive an Air Medal if they flew enough missions. On one mission in early April, Arnold had a lawyer in his backseat for some action near Hue. Right before he rolled in to attack his target, he saw a long orange flame from the ground followed a split-second later by a barrage of sparkling blue tracers of anti-aircraft artillery streaking past the airplane.
A high-pitched squeal came from the back seat: “My God, they’re shooting at us!”
“I think we made them mad,” Arnold said as he dropped his bombs. Unnerved by the scene, the lawyer decided he didn’t covet an Air Medal enough to try flying again.
Despite the heavy ground fire, the F-100s were so speedy that the North Vietnamese rarely hit them. However, when they did get hit, the fragile airplanes often crashed. Fortunately, most pilots were able to eject, and even though Arnold’s squadron lost two airplanes while he was at Tuy Hoa, both pilots survived and were rescued by US forces. One shot-down pilot was flying a mission to support fighting at an air base near the Cambodian border and when he ejected, he landed on the runway below. Bullets and shells flying around him, the dazed pilot scrambled toward what he thought was friendly territory. As he neared a ditch, the outstretched hands of US soldiers pulled him to safety, and then handed him a rifle and told him to start shooting back. He complied.
