Twelve days later, on August 23rd, 1919, Butler gave another dazzling display of flying at Unley. He used the Unley Oval as a landing field, and made the huge crowd of over 20,000 gasp each time he came to land on that restricted area.

And on Tuesday, August 26th, 1919, he launched the first Australian Peace Loan in typical fashion. While speeches were being made in Flinders Street, and having little effect, he arrived overhead in the now famous Red Devil. He buzzed the delighted crowd and then swept low and threw out quantities of loan pamphlets that were eagerly snatched up as they drifted to the ground. This publicity and promotion work formed the major part of Harry Butler’s flying activity during this period.

The Red Devil was a familiar sight at Glenelg and other seaside towns, skimming over the water, and leap-frogging over jetties. A special leaflet for the Peace Loan was dropped over Glenelg on September 16th, 1919.

After jetty-jumping trips from Marino to Outer Harbour, Butler would buzz the Adelaide Children’s Hospital, and nurses rushed to place little patients on the lawns to watch the display.

On September 6th, 1919, he gave an aerial display at Kadina Race Course as the major attraction in a day designed to raise funds for the Kadina Memorial Park. The weather was wet and boisterous, and he flew at considerable risk, but his only comment before getting into the air was, “If it’s good enough for all you people to come out, it’s good enough for me to go up”. And he did.
