What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Pilot was participating in a balloon competition. After passing over the target, he proceeded to land. Pilot made a relatively steep approach due to the need to approach a field over trees. Pilot landed firm, but not hard. The event flight crewmember onboard (not experienced in balloon operations) complained of a sore ankle after the landing and received medical attention. It appeared that the event flight crewmember's foot may have been between the fuel tanks on landing and twisted. Medical personnel initially believed that she had a sprained ankle. Two days after the landing, she received further medical attention and a hair-lime fracture in the bone above her left ankle was discovered.
