If you think about it, the more flying they convince AAG they can do, the more pilots they must get to keep the house of cards from collapsing. It's like a junkie who develops a tolerance for their drug and must ingest higher doses of the drug for the same effect. Eventually, the junkie cannot support their habit and a predictable path to destruction occurs.

At this point Envoy HAS to bring in as many pilots as they lose or they are in trouble and with each increase in flying (the "habit"), the more of the "drug" (pilots) they need.

The question is how long can this vicious cycle continue ?
