NTSB narrative

The balloon pilot said that when he took off, the wind was calm. After about 15 minutes of flying at 1,000 feet agl, he noticed other balloons at lower altitudes traveling at higher ground speeds. The pilot descended to 200 to 300 feet agl and estimated the wind at that altitude to be in excess of 30 knots. After flying at this altitude for about 10 minutes, the pilot decided to land in an open field. During the high wind landing, one of the two passengers sustained a serious injury. The pilot said that about 15 minutes after the landing, the winds were again calm.

Probable cause

The pilot's improper planning/decision. The weather condition (sudden high wind) was a related factor.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: investigation status, damage. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
  • API snapshot SHA-256: 0ec907e328d672b2228601711f7aed3c0984c84eea5f4afcf76aeee63274b66c; retrieved 2026-09-21T12:39:11.479Z.
