the pilot's diverted attention that resulted in the inadequate handling of the burner during ground operations.
Aircraft on the NTSB record: Balloon Works FIREFLY 11 · serial F11-006
An unforecast encounter with a low level microburst that resulted in a distortion of the balloon envelope, an excessive outflow of hot air (loss of lift), creating an excessive rate of descent that was beyond the performance capability of the balloon to recover in the altitude available. The failure of a passenger to follow the emergency procedures directives of the pilot was a factor in this accident.
