Titan have to agree on levels of experience. Less experienced pilots are willing to fly for lower pay than those who have done the time. If one reads the prelim report on the positioning flight to PMB from DBN it is clear that the wrong engine was shut down. The PIC was involved in a similar incident just a year or two earlier. Now does that speak to training (which is expensive) or to experience (which does not come cheap). Once again, follow the money, and you'll find the problem.
