I will make this observation, at the risk of over generalizing.... This flight was operated under FAR part 135, (I think), and therefore not subject to the ATP requirement for passenger Part 121 operations in the US.
Here is a positing from Air Cargo Carriers on AirlinePilotCentral.com regarding pilot hiring.
Is Hiring?: Yes Next Estimated FO Hiring Event: July 2017
First Officer Requirements: Commercial MEL Rated/500 TT (preferred)
Starting May 1st, 2017-
If you take a low time pilot, minimal experience and add to that minimal training at the carrier, then we are likely to see more of these accidents. The available pilot pool is very dry now and if have a pulse and license you get hired somewhere. It's great experience, if you don't have an accident like this one. I think airfreight pilots make some of the best pilots out there. It is a very unforgiving type of operation and requires constant vigilance to stay safe. The learning curve is very steep, especially for the inexperienced.
I think we need to get used to seeing more of these, unfortunately.
