This most interesting photograph was taken December 1934. It shows the Handley-Page aircraft HF42 “Horatius” carrying mail on the first leg to Paris of the inaugural flight to Australia.
It should be noted after impressive service “Horatius” was destroyed in a forced landing at Devon in November 1939.
