No. 200 Flight was a Royal Australian Air Force special duties flight of World War II. The flight was formed in February 1945 to support the Allied Intelligence Bureau (AIB) and saw action over Borneo and the Netherlands East Indies (NEI) from March that year until the end of the war in August. No. 200 Flight was disbanded in December 1945. History From late 1943 B-24 Liberators of the United States Army Air Forces (USAAF) 380th Bombardment Group were used on occasion to support Allied special operations units in the South West Pacific Area. In July two No. 24 Squadron RAAF B-24s were also modified to drop special operations personnel and conducted operations from Hollandia in this role during August. In June 1944 it was proposed that a specialised RAAF unit be formed to provide air transport for the AIB's Z Special Unit. This proposal was supported, and No. 200 Flight was formed at Leyburn, Queensland on 20 February 1945. Many of the flight's air and ground crew were transferred to it from No. 99 Squadron. The flight was controlled by the AIB and was tasked with the insertion and supply of intelligence gathering parties behind Japanese lines. Due to the secrecy of these tasks personnel from the flight were forbidden to speak about their duties at any time. No. 200 Flight's six B-24 Liberators had been modified for the unit's specialised role. The main changes were the removal of the mid-upper and ball turrets and all armour plate, the replacement of the normal radar with a Rebecca radio set and the installation of a slide at the rear of the aircraft to drop personnel and supplies. No. 200 Flight began training operations with Z Special Unit immediately upon formation. Despite the priority accorded to the unit, it experienced shortages of equipment and its accommodation and maintenance facilities at Leyburn were basic. By mid-March No. 200 Flight had a strength of nine eleven-man aircrews, 450 ground crew and six B-24s. The flight began its first operations on 15 March 1945. On that day three B-24s (A72-191, A72-159 and A72-192) departed Leyburn for McGuire Field in Mindoro, where they arrived on 18 March, via Darwin and Morotai. After unsuccessful attempts on 21 and 22 March, two B-24s (A72-191 and A72-159) dropped a party of eight Z Special Unit personnel and equipment near Bario on 25 March but the aircraft (A72-191) flown
