Awarded the Pilot Flying Badge on January 22, 1943.
Assigned to the 414 Squadron, Royal Canadian Air Force on August 29, 1943.
B.P.S.O., A.E.A.F., reported that Spitfire aircraft IXB.416, piloted by F/Lt. J.C. Younge of No.414 R.C.A.F. Squadron, left base on the 6th September, 1944, to carry out a Tactical Reconnaissance of the Dunkerque (France), Brugge (Belgium), Gent (Belgium) area. Cloud and accurate FLAK (German Anti Aircraft) encountered at Brugge caused the accompanying pilot and F/Lt. Younge to separate but contact was regained at Gent, Belgium, on the R/T. F/O Loundes, a pilot from No.430 R.C.A.F. Squadron, who was in the area was contacted by an army scout car and asked if he could stop a barge load of enemy troops crossing the river South-East of Gent. Owing to shortage of petrol, F/O Loundes returned to base but he heard F/Lt. Younge say that he had indentified the barge and was last heard saying something about his jet tank. No further news was received after this from F/Lt. Younge and in view of this information, he was classified as "Missing". This incident occurred at approximately 1100 hrs on the 6th September, 1944.
