Analysis

While executing a landing in an open field, the balloon encountered unfavorable winds resulting in an increased sink rate. The pilot did not adjust for the balloon's increased sink rate in time to prevent a hard landing during which one passenger suffered a broken ankle and subsequent hospitalization in excess of 48 hours.
