Born in Lloydminister, Saskatchewan, L.A.C. Karl Aalborg trained as a bomb-aimer at #5 Bombing and Gunnery School in Defoe, Saskatchewan from 9 November, 1942 until 4 July, 1943 flying in Anson and Bolingbroke aircraft.
After travelling overseas, he was posted to #82 Operational Training Unit where he joined the crew of F/Sgt. R.J.L. Banks and completed O.T.U. training aboard twin-engined Wellington bombers during the period from 29 July, 1943 to 22 September, 1943. Following his O.T.U. experience, F/Sgt. Aalborg was noted as, "above average" as both a bomb-aimer and an air-gunner. Notes in his logbook refer to him as, "very keen and very conscientious" and that he, "should do well on operations."
The crew then flew aboard four-engined Stirling aircraft at #1651 Heavy Conversion Unit from 1 November, 1943 until 10 January, 1944.
Despite having no operational experience, the crew was selected for training at the Pathfinder Force Training Unit at Warboys. F/Sgt Aalborg completed the Pathfinder Force navigational training course on 20 February, 1944.
The crew was then assigned to No. 7 Squadron PFF in the Royal Air Force. Sgt. Banks' crew completed 36 operations, the first being to Essen on 26 March, 1944. Aalborg listed his crew position as NAV 2 while on operations with the Pathfinders.
F/L Aalborg and his crew were lost on their 37th operation aboard Lancaster NE-126 (MG-R). Seventeen of 378 Lancasters were lost on this operation to Frankfurt on 12/13, 1944. The raid was reported to have been very successful. F/L Aalborg's aircraft took off at 1913 from Oakington and was reported to have crashed at 2300 at Damscheid about three km WSW of Oberwesel, a small town on the west bank of the Rhine River, six km NNW of Bacharach. All aboard were killed and are buried in the Rheinberg War Cemetery.
