Otto Gaiser

Otto Gaiser (5 October 1919 – 22 January 1944) was a Luftwaffe ace with 66 confirmed kills, and he was the recipient of the Knight's Cross of the Iron Cross during World War II. The Knight's Cross of the Iron Cross was awarded to recognise extreme battlefield bravery or successful military leadership.

In 1942, Gaiser was assigned to Jagdgeschwader 51 (JG 51—51st Fighter Wing) where he served as Rudolf Wagner's wingman. Wagner went on to become a Luftwaffe ace as well. Gaiser claimed his first kill on 16 March 1943. That day, he shot down a Soviet Lavochkin-Gorbunov-Gudkov LaGG-3 fighter near Vyazma. Gaiser served with 10. Staffel of JG 51 which at the time was under the command of Oberleutnant Horst-Günther von Fassong. He achieved his 10th victory on 11 July, when he claimed another LaGG-3 shot down. Gaiser claimed 17 victories in August, including five Soviet Ilyushin Il-2 ground-attack aircraft shot down on 14 August, making him an "ace-in-a-day".

On 22 January 1944, Gaiser was last seen in combat with Ilyushin Il-2 ground-attack aircraft near Berdychiv, Ukraine. He has remained missing to this day. It is thought he became a victim of the Soviet ground defences. On 9 June 1944 he was posthumously awarded the Knight's Cross of the Iron Cross (Ritterkreuz des Eisernen Kreuzes) and promoted to Leutnant. Before his death, Gaiser was credited with 66 victories in 380 missions. All his air victories were achieved over the Eastern Front (World War II) and included 21 Il-2 Sturmoviks.
