The NTSB's narrative final · quoted from the NTSB record
AFTER 30 MIN OF FLT, THE PLT LNDD THE BALLOON IN A DESERT AREA. THE CHASE CREW WAS UNABLE TO REACH THE AREA, SO THE PLT ELECTED TO FLY THE BALLOON & PSGRS TO AN ACCESSIBLE AREA. MOMENTS AFTER LIFT-OFF, A FUEL LINE CONNECTION FAILED & A FIRE ERUPTED. THE PILOT TOLD THE PSGRS TO JUMP; 1 PSGR JUMPED (OR FELL) FROM A RELATIVELY HIGH ALTITUDE & WAS FATALLY INJURED. AN EXAM OF THE BALLOON REMAINS REVEALED THE FUEL SYS WAS MODIFIED TO A CONFIGURATION THAT WAS NOT APPROVED BY EITHER THE FAA OR THE MANUFACTURER. ONLY TWO FUEL TANKS WERE ORIGINALLY APPROVED FOR THIS BALLOON; FOUR FUEL TANKS WERE INSTALLED & TWO OTHERS WERE LOOSE IN THE BASKET. THE FUEL MANIFOLDS FOR THE INSTALLED TANKS WERE OF AN UNKNOWN DESIGN & ORIGIN WITH HOSES & FITTINGS THAT DID NOT MEET FACTORY SPECIFICATIONS.
