Aircraft involved

Probable cause & findings

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.

Factual 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. Source: NTSB Aviation Accident Database Retrieved: 2026-02-12
