Not sure about Bristow Academy, but there's more US helicopter instructors teaching Germans and Norwegians than US students in proportion. Thus looking to me like all the heli students being trained by Americans SHOULDN'T BE HERE TO LET AMERICANS HOURBUILD ON THEM DAMN FAST. Right?
(KHIO -main part of Hillsboro Aviation. Not sure about numbers in KTTD since it's not for M1/J1 students)
Well considering the balance of German, Austrian and Norwegian instructors working at KTTD teaching nothing but American students... well... guess it all works out in the end.
