Ab Initio programs suck because they'll let anyone with enough money go through them. The hurdle to jump in order to get your ratings is how much money do you have, and how much time do you have.

The military produces experienced pilots in a short amount of time because these individuals have been screened on multiple levels before they even get an opportunity to strap on a jet. The one's that aren't up to the high standards of military flying, get washed out. It's as simple as that.

In ab initio or most other civilian flight training, those that aren't up to the standard....try and try again, throw more money at it and most will eventually get the rating.

In the military, if you don't cut it, if you aren't good enough, you're done.
