United and TWA experimented with a "cadet" program in the '60s when any kind of pilot was needed. They found it was a waste of time, almost all of those who were taken up failed to get to CPL level. The considered wisdom was that if one wanted to be a pilot, one would take the initiative to get the CPL on his own. Admittedly, testing then was pretty crude. Has never been done since. This from a TWA Chief Pilot back in the late '70s.
