I wouldn't rubbish the idea of a QF Cadetship starting up again just because there are "good applicants" from regional airlines or elsewhere.
The QF Cadetship was a strong 50+ year program that churned out high quality pilots from an ab-initio position thru to MECIR and placement. It still has its place, a Cadetship hasn't been run since 2010 so for the last 6 years where have the high calibre applicants been going?
A real shame IMO! We should be nurturing young aviators and encourage striving for excellence in our profession and the sooner that program restarts the better.
