As the Tet Offensive kicked off, the Air Force halted all flights to, from, and inside Vietnam not directly related to combat operations. Arnold was supposed to fly into Cam Rahn Bay once flights resumed, but the first flight available was a bright orange 707 to Tan Son Nut Air Base operated by an airliner on contract with the Air Force, so he took that instead. However, getting to Tan Son Nut was just half the battle. Tuy Hoa was in the middle of the country, and the Air Force had a regularly scheduled shuttle flight from Cam Rahn Bay to Tuy Hoa, but not from Tan Son Nut. When Arnold arrived, it was late afternoon, so he headed to the Visiting Officers Quarters to get some rest before tackling the next leg of his trek.
Anxious to get into the fight, Arnold walked back to Base Operations the next morning. He had no plan, but he figured that, given the small world of the US Air Force, he would work something out. He was right. As soon as he entered the operations building, he bumped into one of his pilot classmates from the Fairchild survival school.
“What the heck are you doing here?” asked the astonished pilot.
“I’m trying to get to Tuy Hoa.”
The other pilot was flying a C-123 “Provider” cargo airplane, but he wasn’t authorized to carry passengers. However, the C-123 pilot wasn’t about to let an ill-thought-out rule stand in the way of practicality, so he invented a reason to fly to Tuy Hoa along with a job for Arnold so he could fly on the airplane as a crewmember.
Arnold disembarked from his hitchhiking steed at Tuy Hoa a few hours later and checked in with his new squadron, the 308th Tactical Fighter Squadron. The squadron, part of the 31st Fighter Wing with motto Return with Honor,” was nicknamed the “Emerald Knights,” complete with bright green scarves and patches.
