the crew of Vickers Wellington OJ-F 'F for Freddie'. Wellingtons and their crews from the resident No. 149 Squadron, coded OJ, were used for the filming. The exception to this was Percy Pickard who was at that time Squadron Leader with No. 311 (Czechoslovak) Squadron. Pickard played the part of Squadron Leader Dickson, the captain of 'F for Freddie'. Pickard would go on to lead daring raids such Operation Biting and the later Operation Jericho on Amiens Prison, in which he was killed. Postwar (1945–1950) After the war, aircraft from Mildenhall flew home repatriated prisoners of war in Operation Exodus, and participated in Operation Manna, dropping relief supplies to the Dutch people stranded by the flooding caused by the retreating German . By the end of 1945, Mildenhall's operational activity experienced a drastic decrease and despite a brief flurry of flying activity in the late 1940s, the RAF reduced the base to 'care and maintenance' status. The only remaining RAF unit of significance was Headquarters No. 3 Group, part of Bomber Command, which remained on station until 1967. The following RAF units operated from Mildenhall: No. 1 Engine Consumption Unit RAF No. 3 Blind Approach Training Flight RAF No. 3 Group Communications Flight RAF No. 4 (Bomber) Group RAF No. 5 (Bomber) Group RAF No. 25 Heavy Glider Maintenance Section RAF No. 32 Base RAF No. 149 Conversion Flight RAF No. 401 (Meteorological) Flight RAF No. 1503 (Beam Approach Training) Flight RAF No. 1505 (Beam Approach Training) Flight RAF Engine Consumption Unit RAF Regional Control School RAF Cold War (1950–1991) Strategic Air Command The initial Strategic Air Command unit to use Mildenhall was the 7511th Air Base Group (later redesignated 3910th Air Base Group), being activated on 11 July 1950, to prepare the facility for operational use by SAC aircraft. On 1 May 1951, SAC took control of the station rotated bomb wings in and out of Mildenhall on temporary duty assignments. The first operational strategic unit to use the airfield was the Boeing B-50D Superfortress equipped 2nd Bomb Wing, arriving on Temporary Duty (TDY) from Hunter AFB in Georgia on 4 May 1951. Other rotational strategic bomb wings at Mildenhall were: 22nd Bombardment Wing (7 September 1951 – 12 December 1951) (B-50D, KB-29P) (TDY from March AFB California) 93rd Bombardment Wing (16 December 1951 – 8 March 1952) (B-50D, KB-29P) (TDY from Castle AFB California) 509th Bombardment Wing (4
