I would sure hate to have to answer in an interview what happened when I broke a training contract. Or have creditors come after me. Or get sued and taken to court. Even if I could fight it and win, or even if Mesa didn't come after the money at all, it's still a risky proposition in the probably small chance that Mesa decided to make it painful for people. With 45 days notice the debt is halved...it's not that much money after it is prorated then halved.
