2. MkIIc LB640 was used by the USAAFs 346th Fighter Squadron, 350th Fighter Group, in Sardinia from 29 February 1944. It was operated as a target tug, but also to give fighter-style flying experience to groundcrew members, and as a rapid liaison aircraft. Two further Hurricanes were converted for the P-39 Airacobra-equipped groups other squadrons, the 345th FS example on one occasion landing on a Sardinian beach to rescue a downed P-39 pilot.KEY COLLECTION

3. LB640s late-war cockpit configuration in AAF service looks similar to how the Hawker Restorations aeroplane will appear once the conversion is completed, with a pair of two-panel canopies.KEY COLLECTION

4. The only factory conversions of a two-seat Hurricane were the two MkIIcs for the Imperial Iranian Air Force, which were undertaken by Hawkers Langley, Berkshire, facility in 1946-47. A rear cockpit canopy, taken from a Hawker Tempest, was added prior to delivery, but after this shot of serial 2-31 was taken on a test flight.AEROPLANE
