G-ADHJ  Short S.20 Mercury                  (c/n  S.796)

                                    

                                        Interesting shot from the R.S. Robinson collection (via the Civil Aviation Historical Society in
                                        Melbourne) of the top element of the Short-Mayo Composite on a misty morning on the Medway
                                        at Rochester in 1937.    Piggy-backed onto the top of the S.21 Maia, several experimental mail run
                                        flights were made with this sleek looking four Napier Rapier VI engined floatplane.   In addition to
                                        the Atlantic seperation-from-the-mother-ship flights the mail carrier aircraft also several unattached
                                        flights to Africa before being broken up in 1941.
