AFTER THE ACCIDENT THE PLT REPORTED THAT HIS PASSENGER WAS IN A 'HIGHLY EXCITED STATE' BEFORE TAKEOFF ANDWANTED TO TAKEOFF EVEN THOUGH THE WEATHER WAS NOT GOOD ALONG THEIR ROUTE OF FLT. THE PLT ALSO SAID THE PASSENGER IN THE FRONT SEAT DISAPPEARED FROM HIS VIEW AS THE ACFT REACHED 300 FT. AFTER THE CONTROL STICK EPISODE THE PASSENGERS HEAD REAPPEARED. POST CRASH INSPECTION OF THE ACFT REVEALED NO MALFUNCTIONS OF THE CONTROLS OR ENGINE. THREE DRUGS WERE FOUNDIN THE BAGGAGE OF THE PASSENGER; DEXEDRINE 5MG, TRANSDERM-SCOP 4'S, AND COMPAZINE 5 MG.
