The NTSB's narrative final · quoted from the NTSB record
ACCORDING TO THE PILOT SHE RECEIVED WIND INFORMATION FROM A FLIGHT SERVICE STATION, THE NOAA AND ATIS APPROXIMATELY 1.5 HOURS PRIOR TO TAKEOFF. ALL THESE SOURCES PREDICTED WINDS TO BE LESS THAN 7 KNOTS. WINDS WERE 'VERY LIGHT' DURING BALLOON INFLATION. THE LAUNCH WAS UNEVENTFUL UNTIL THE BALLOON ROSE ABOVE THE TREES WHERE THE VELOCITY OVER THE GROUND INCREASED TO AN EVENTUAL 17 KNOTS. THE CHECK PILOT THEN INSTRUCTED THE PILOT TO SKIM THE TOPS OF CORN IN A CORNFIELD TO SIMULATE A TOUCH AND GO LANDING. THE FIELD SHE SELECTED WAS ON THE FAR SIDE OF A SET OF POWER LINES AND A WOODED AREA. AS SHE CLEARED THE POWER LINES THE WIND SHIFTED TO A HEADWIND AND THE BALLOON DESCENDED INTO THE TREES IN SPITE OF A PROPANE BURN TO ARREST THE DESCENT. THE BALLOON ENVELOPE WAS DAMAGED BY THE TREES.
