From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

High rate of decent caused balloon to hit hard causing the injuries and then bounce twice before dragging to a stop. Pilot had requested weather information less than 1 hour before takeoff. The gus front they encountered from storms located 40 miles north was not forcasted for his intended flight.
