RedactedNarrative: THE OPERATOR OF V1 WAS ON PLANE AND DID NOT SEE V2.  WHEN THE OPERATOR OF V2 SAW THAT V1 WAS GOING TO HIT HIM, OPERATOR 2 JUMPED IN THE DRIVER SEAT AND STARTED THE MOTOR AND BACKED V2 APPROXIMATELY ONE FOOT BEFORE THE CRASH OCCURRED IN AN ATTEMPT TO GET OUT OF THE WAY. V1 STRUCK V2 ON THE STARBOARD SIDE, AT THE DRIVER'S CONSOLE, THEN CONTINUED ACROSS THE TOP OF V2. THE OPERATOR OF V1 SAID HE NEVER SAW V2 UNTIL HE HIT AND SAW OPERATOR 2'S ARMS GO UP BUT EVEN THEN CLAIMED HE DID NOT SEE V2.
