Although, we greatly enjoyed the challenges involved in the past year or so, both my wife Pat and I were exhausted in many ways. The fun had gone.

Keith Willcox, John Holmes and I began designing a 50ft.fabric balloon. We were slowly progressing but finally gave up. Keith headed overseas. I began experimenting with tethered blimps,(see below) and began learning to fly light aircraft.

Testing a design in water to see how pressure affects balloon shape. An iron weight hangs below to add pressure to the air inside. Keith & I testing a 12 ft long blimp. We used helium as the lifting gas, expensive, but safe and easy to use. Leakage was a big problem. A 25 ft long blimp, which used ammonia as a lifting gas.
We found ammonia cheap, but likely to cause burns to the eyes in particular. The cylinder had to be heated to evaporate the liquid ammonia within.

My only active involvement with ballooning since, was helping Phil Kavanagh launch his early balloons. I then left Australia and worked in London for two years. On return, I made two parachute jumps from his first fabric balloon "Ulinga". The last from 12,000 ft for a long glide down.
The Aerostat Society continued for a while, however there appeared to be a number of groups forming, the details of which I leave to others.Terry McCormack began working on other balloons.
Few people ever saw balloons fly during those years, unless they ventured into the countyside. Understandably, few advertisers considered sponsorship worthwhile. That situation has now completely changed.The sport is now much safer and predictable, due to pilot training regimes, the improved ability to control altitude, and more reliable weather and wind predictions. The ability to now fly safely over Australian cities not only attracts far more sponsorship, but brings the beauty and wonder of ballooning to many.
