VH-THA     Hiller 12-C                                                   c/n  769

                                         One of two Hillers operated by TAA in their experiments with helicopter operations.
                                         (The other was VH-THB).      This shot was taken at Essendon in 1957 whilst the
                                         machine was being used for training.  The problem with photographing helicopters is
                                         that, in order to encompass the whole of the rotor, the fuselage is then unrealistically too
                                         distant!    These choppers went to the New Guinea sphere of operations, and VH-THA
                                         was sold to Crowley Airways in the later 1950s.  Its fate is unknown.
