The NTSB's narrative final · quoted from the NTSB record

The pilot of the balloon reported that after three unsuccessful landing attempts during the sightseeing flight, he located a grassy 2-3 acre field and positioned the balloon for landing. He stated that the approach was from the northwest at 500-feet and the balloon was traveling about 6 knots. The pilot anticipated winds near the surface to be from the east; however, after descending to 250-feet the balloon continued in a southerly direction, near trees. The pilot executed a controlled descent over a tree and landed firmly. The basket bounced once and came to rest upright with the balloon's envelope against a tree. After the landing, one of the passengers complained of ankle pain and was transported to a hospital. A medical evaluation revealed that the passenger's ankle was fractured. The pilot reported that a passenger landing briefing was completed prior to landing.

About this page

Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The documents and photographs are the NTSB's docket, the folder of records gathered during the investigation, shown as the NTSB released them (the NTSB redacts some personal details first) and listed under the NTSB's own titles. This site's own text never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number WPR10CA058.
