There are now Direct Entry Captains.
A 777 Capt who decided not to sign up for RA65 (a one time offer, never to be repeated), retired. He became a sim instructor. Now he is to rejoin as a 777 Capt, to be fast tracked back into training. He knows the GMA from their time at Ansett together....
So, he takes a command, thus shafting a SFO out of a Cmmnd, shafting a SO out of promotion to FO and shafting a GA pilot out of the dubious honour of joining CX, shafting a licence holder out of their first flying job....
