NTSB narrative
The pilot of the balloon reported that, after landing and while the ground crew were in the process of securing the balloon, the driver of the chase truck attempted to help secure the balloon by grabbing a rope tethered to the balloon. While placing the rope in the rope’s storage bag, the balloon unexpectedly ascended, and the driver’s glove became entangled between the rope and bag. The balloon ascended about 20 ft in the air, and while the pilot was pulling the red line to top the ascent, the driver’s glove released from the rope and bag. The driver fell to the ground sustaining a serious injury. The pilot subsequently landed the balloon without further incident or damage. The pilot reported no mechanical failures or malfunctions with the balloon that would have precluded normal operation.
Probable cause
The pilot’s failure to maintain control of the balloon and a member of the ground crews entanglement with a tether rope, which resulted in a serious injury when they fell to the ground after the balloon unexpectedly ascended.

- 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: local date, investigation status, cause areas, damage. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2020-11-29.
