SOAR XXXVII, Las Vegas, 2013. Attendees talk across a display table while the militaria vendor row — lapel pins, sew-on and hook-and-loop patches, and tables of unit ballcaps — runs the length of the ballroom behind them. The T-shirt at center, sold by the Tennessee Museum of Aviation, depicts the Douglas A-1 Skyraider. The piston-engined 'Spad' provided close air support and escort for MACV-SOG reconnaissance teams operating across the Laotian and Cambodian borders, and its crews remain closely tied to the SOG veterans' community. Flags of the United States, Canada and the former Republic of Vietnam hang overhead. Project: 219861
