At 05:40, a Kavanagh B-425 balloon registered VH-OKX, with 15 passengers and one pilot onboard, lifted off in conditions that were reported to be a light north-westerly wind, at about 5 kt. Three other balloons launched soon after OKX.
OKX maintained 40 ft above ground level (AGL) for about 5 minutes, then climbed to about 2,500 ft AGL. The balloon was then carried in an east-south-easterly direction over undulating country in the general direction of Maitland. The pilot stated the wind direction changed and the speed increased at about 0600, which was significantly earlier than he expected.
The balloon pilots communicated with each other regarding the wind speed and decided to land at the first suitable site. The predetermined landing areas were no longer available to them, as the wind change had taken them further east than they had planned. The area selected was a large open field that was not one of their normal landing areas.
The pilot of OKX reported that the balloon descended gradually over the next 15 to 20 minutes, and the balloon’s speed increased. He briefed the passengers for landing and advised them to rest their backs on the basket padding and hold on to the internal grab handles as per their previous briefing. The passengers maintained that position for the duration of the landing. The balloon approached the landing site about 4 km south of Greta, with a ground speed of about 20 kt.
As the balloon descended into the centre of the clearing (several feet above the surface), the pilot turned off the gas to the burners and opened the envelope deflation system. The balloon landed lightly with the basket upright, then the basket laid over onto its side and was dragged across the field by the balloon envelope acting as a sail in the wind.
The pilot stated that following the landing, the balloon changed direction slightly and was dragged about 40 m towards a large bush in the centre of the field. The basket subsequently contacted the bush, lifted up rapidly on its right side and landed back down heavily. It was then dragged a further 50-60 m before coming to rest (Figure 2). Due to the significant ground impact forces, one passenger was seriously injured and three others sustained minor injuries. All four passengers were taken to hospital for examination, with three being discharged on the same day.

- Shortly after take-off, the balloon experienced strong winds and turbulent conditions, as predicted in the Bureau of Meteorology graphical area forecast and grid point winds and temperature forecast. Consequently, the balloon deviated from its intended flight path and landing area. Due to the adverse conditions, the pilot decided to land at the first suitable site, which was a clearing that was unfamiliar to him.
- Due to the wind conditions, the balloon landed with a significant forward velocity and was dragged for a considerable distance on its side by the balloon’s partially deflated envelope. As the basket was being dragged, it struck a large bush, forcing it upwards before impacting the ground with considerable force that resulted in injuries to four of the passengers.
