flight safety
we have had on the uk register bell 47 ex uk military with full pt cof a also ex uk mil as3130 ex yugo 341g ex mill hillers ex swiss mil allouettes
where it seems to get cloudy is when aircraft have special engines / modifications ie ex uk mil gazzelles .ex french mil allouettes .ex us hueys, th55,th57,oh58 ect
did not some of the oh6 [hughes 500,s ] go on the us register as these were production helis
some one in the us must know more about this regarding us ex mil
