Harry Butler’s appeal was not limited to the man in the street. Sir Henry Galway, who was always a good friend to men of courage and enterprise, effectively demonstrated his faith in Butler’s ability by travelling as a passenger in the Avro bi-plane on February 3rd, 1920. The flight, lasting 40 minutes, took the Governor from Parafield to Mount Lofty, along the foothills to Glenelg, north following the beach to Port Adelaide, then back to Parafield.
The Governor afterwards spoke enthusiastically of the trip, stating: "…..40 minutes in the air with Captain Harry Butler was the most fascinating 40 minutes I have ever spent……I was tremendously impressed by the wonderful control which Captain Butler has over his machine, and the remarkable cleverness with which he manipulated it. There is no doubt that he is a pilot of the very highest order."
