Unfortunately for the Germans security was breached within weeks. On 1 January 1945, after participating in Operation Bodenplatte to support the German Ardennes Offensive, a Ju 88 (code D5+PT) flown by "Unteroffizier" (Corporal) Lattoch belonging to 9./NJG 3 landed in Luxembourg in error. Lattoch had been present at the briefing on 1 December 1944 and was taken prisoner of war. He was soon handed over to the intelligence branch of the US Ninth Air Force. He divulged the details of the meeting and this information was passed to the Air Ministry.
