The NTSB's narrative for the Balloon Works FIREFLY 7 final · quoted from the NTSB record

TWO HOT AIR BALLOONS WERE INVOLVED IN A MIDAIR COLLISION DURING A SANCTIONED BALLOON COMPETITION. N40363 WAS ABLE TO RETAIN CONTROL AND LANDED UNEVENTFULLY. N1505F PARTIALLY DEFLATED AND DESCENDED OUT OF CONTROL TO THE GROUND. WITNESSES STATED THAT N40363 WAS THE HIGHER OF THE TWO BALLOONS AND APPEARED TO BE DESCENDING. N1505F WAS RISING AND MOVING OVER THE GROUND AT A FASTER RATE. THE GONDOLA OF N40363 CONTACTED THE ENVELOPE OF N1505F AND RIPPED A PORTION OF THE FABRIC. THE PILOT/PASSENGER OF N1505F REPORTED THAT THE PILOT, UPON CONTACT WITH N40363, PULLED THE EMERGENCY RIP PANEL, TURNED OFF THE PROPANE, AND BEGAN TO PREPARE FOR A HARD LANDING.

Everything on this page comes from the NTSB's public records. The narrative, probable cause and findings are the NTSB's own words; the coded tables behind the report are written out in plain English, with pilots' ages, home towns and medical details left out. The documents and photographs are the NTSB's docket, shown as the NTSB released them. This site's own text never names anyone involved. A preliminary report can change; the final report usually follows one to two years later, and the page is refreshed when it does.
