What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
August 10, 2019, time was 0845, balloon festival at privacy data omitted, Galt California. Public display and tethered balloon rides to the public.
After multiple successful earlier tether rides, the three tethered balloons decided to end rides due to increasing wind and potential thermal activity. Balloon was tethered to three trucks, and was suddenly lifted by wind (false-lift), to approximately 50FT, (only the pilot was on board), and one rope snapped, then a second. Balloon was held by only one rope, and began to twist. Pilot ordered the last rope to be cut for safety and began a flight, unfortunately towards power lines. Pilot applied burner heat to rise over the wires which also burned a panel of the nomex fireproof skirt above. After safely avoiding the wires he chose to land immediately in the next field. The balloon was not fully inflated by this point and the decent was fast with a hard landing.
Pilot exited the basket and was attended to by emergency services and diagnosed by a neurologist with a tailbone "simple compression fracture of L1".
