THE OWNER OF THE HOME BUILT ACFT HAD PURCHASED IT FROM THE BUILDER. HE POSSESSED NEITHER AN FAA MEDICAL, NOR A PLT CERTIFICATE, & HAD NO PREVIOUS FLT TIME IN THIS MAKE & MODEL OF ACFT. HE TOLD A WITNESS THAT HE INTENDED TO TAXI IT (PRESUMABLY FOR FAMILIARIZATION). SUBSEQUENTLY, THE ACFT BECAME AIRBORNE & REMAINED WITHIN ABOUT 1/2 MI OF THE DEP END OF RWY 30.
