NTSB narrative
The pilot said there had been very little wind when he had launched in his balloon earlier and his flight at about 1,000 feet above ground level (agl) was normal. He reported that there was very little wind until he descended to about 300 feet agl when the wind began to interfere. The pilot advised all passengers to lower themselves inside the basket and to brace themselves for a hard landing. The passengers advised that the balloon basket hit the ground “very hard” and bounced several times before hitting the slope side of a dirt hill where the basket flipped onto its side and was dragged in the dirt in that tipped-over position. The total distance from first impact to the balloon's final resting location was estimated at about 1,300 feet. The impact resulted in substantial damage to the main basket, the basket partitions, and substantial damage to the burner cage.
Probable cause
The pilots’ encounter with increased wind, which resulted in a hard and fast landing.

Source notes (5)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
- API snapshot SHA-256: 2c9942dda939b989c8433dfd2f41d38563f2a62c28e81b8db62466764090c67a; retrieved 2026-09-15T22:00:13.900Z.
- Corrected after a review of the NTSB narrative, which states these values explicitly: damage. The narrative states the impact "resulted in substantial damage to the main basket, the basket partitions, and substantial damage to the burner cage".
