## Analysis

THE ACCIDENT OCCURRED DURING A FLY-IN. SEVERAL HUNDRED SPECTATORS WERE AT THE ARPT. THE ACFT LIFTED OFF RWY 18 IN A NOSE-HIGH ATTITUDE, THE LEFT WING DIPPED DOWN & THE ACFT SETTLED BACK TO THE GROUND IN A NOSE-HIGH ATTITUDE. THE ACFT IMPACTED ABOUT 50 FT EAST OF THE RWY HEADING SE & THEN SLID ABOUT 200 FT ACROSS THE GRASS BEFORE HITTING THREE SPECTATORS WHO WERE POSITIONED ALONG A LINE 200 FT EAST OF THE NORTH RWY. THE PLT STATED THAT A RADIO CONTROLLED MODEL AIRPLANE APPEARED IN FRONT OF HIM JUST AFTER LIFT-OFF & HE INSTINCTIVELY BANKED TO AVOID THE MODEL. A WITNESS SAID HE SAW R/C'S OPERATING IN THE VICINITY OF THE RWY BEFORE & AT THE TIME OF THE ACCIDENT.
