Check out the Swiss cheese model for further explanations.
Not sure if this is taught in military aviation. Perhaps someone else can chime in there?…..
Per the track of PAT 25 (Captain Steeeve uses the helo sectional to help illustrate all this) has the tracks of both aircraft from ATC radar overlaid on the sectional and one can see that PAT 25 is off the prescribed route even before the turn (and can be seen in the above link from the squawk above).
As former aircrew, I had my head on a swivel as SoCal traffic is horrendous and we had no such thing as ADS-B back then and the two biggest worries we had as rotorheads were fast movers (we often called them suck and blows) running us over from John Wayne or El Toro, or the occasional flights into March AFB (gear down and welded was the reply of the pilot one time when told to check gear down and locked). Flying at night has its challenges and trying to pick out other aircraft below one's altitude is not easy.
The big questions that very well may be unanswered is which aircraft did PAT 25 actually see? The aircraft on departure, the aircraft it ran into, or a 3rd aircraft behind the American Eagle flight that was going to be landing behind the lost flight.
