20th Tactical Reconnaissance Squadron Honor Roll Maj. Roger McLain, a pilot in the 20th TRS at Udorn, Thailand, had this honor roll made in 1967 to recognize the squadron's pilots who had completed their tours. He presented the honor roll to the squadron when he completed his 100 missions. After the war, McLain added the names of those who were captured and killed in action. The purple ribbons noted those who had since passed away as of 2007, when McLain donated the honor roll to the museum. Click here to return to Badge of Honor: 100 Missions Up North.
