The flight and landing sequence
The Australian Transport Safety Bureau's final account describes a sightseeing flight from Royal Park, Melbourne on April 20, 2022, carrying 13 passengers and a pilot. The pilot observed gaps around the balloon's top vent, allowing air to escape without command. During an attempt to reach Elwood Beach, the basket struck two rooftops before descending through trees and coming to rest outside an apartment building. Three passengers sustained minor injuries.

The ATSB found that the modified deflation system leaked at pressures reached in normal operation. It said the manufacturer had made incorrect design assumptions and had not completed the necessary analysis or tests; production testing also failed to expose the fault. The manufacturer subsequently introduced safety actions involving sensor calibration, testing procedures and quality checks.
Those findings come from the later investigation, rather than being inferred from the original rooftop photographs. A safety investigation explains contributing factors and preventive actions; it should not be converted into an unsupported claim about criminal responsibility. The related flight guide concerns passenger travel information, not an assessment of this balloon operator.
