take lookat second prob ability go out ourselves middle desert flying can reduce almost zero have already accepted risk ourselves bad idea initial flight state-of-the-art projects like Bob Campbells B-29 fact such project know has handled exactly way dont necesssarily mean literal desert just some facility space enough allow plenty leeway uncertainties untested airplane Let give some examples

increased first much lower Unfortunately can never get probability crash down zero behooves us keep probability No 2 low can boils down crowd controL mentioned earlier AMA has lifted its 40-pound limitation insurance purposes opposed competition rules did ever include conditiog aircraft over 20 pounds must abide rules Air Show Team operations What boils down must establish flight line flight operations must stay side line spectators other good step toward crowd control need maybe can benefit adding fact Giant Scale operations go bit further specify minimum distance usually 100 ft between spectators flight line Some outstanding examples safe wellcontrolled operations Fly-ins Merwin Ranch California STARS Spangled Rally Olean NY both cases flight line some 300 ft tbe pit spectator areas separation enforced otherwise good flying sites just have space have much separation opinion needed average Giant Scale aircraft What aver age WelL just off top head singleengined weighs 25 27 pounds has wing loading three-quarters one-half normal-size sport Pattern models flies slowly much stable Such aircraft can operated just safely normal model basis observations usually operated safely think reasonable minimum separation flight line spectators RC model would 50 75 ft ant mean models iant Scale upper limit 30 40 pounds Beyond weight limit whatever minimum separation should increased keep risk down keeping probability No 2 low think people build larger especially multi-engined aircraft will agree with have talked wont consider flying creations unless have conditions roughly similar towhat am describing Some people decrying Giant Scale air craft dangerous monsters seem using same arguments heard about half century ago effort made legally ban abominations used gasoline en gines
