As has been proven overseas, there is nothing wrong with cadet programs as long as the company has solid in-house training (post CPL) in place. The real problems will begin when a fresh CPL is more or less 'thrown' into a larger aircraft without much further training other than a type rating.
Until now REX has had the luxury of employing GA pilots with years of command experience. Will the company be able to handle the extra training, etc., required to bring fresh CPLs up to speed in a safe manner?
