Captain Samuel Frederick Henry "Siffy" Thompson MC, DFC (30 August 1890 – 27 September 1918) was a British World War I two-seater fighter ace who, in conjunction with his observer-gunners, was credited with thirty aerial victories (18 destroyed, 12 'out of control')[1] before being shot down and killed.
Despite having an active fighter career of only five months,[1][2] he reached the rank of captain and was awarded two British military decorations.
20 Squadron in late 1917, Thompson's career started somewhat awkwardly, as he crashed his aircraft on 27 October, after which he was transferred to No.
