What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) During approach for landing balloon crossed over a paved parking lot. The heat being radiated created a thermal which caused the envelope and basket to begin rotating. The significant outside air temperature rise around the envelope exaggerated the descent and created an environment which the pilot could not generate sufficient heat to climb the balloon away using the acft's burners. The envelope contacted electrical wires and initiated a post impact fire in the envelope.
