$10 says Mr. Roush was at fault here, and that the controller(s) also failed to recognize a problem with the pilot (Mr. Roush) understanding what was expected with his required specific approach rpocedures, possibly from a lack of experience operating that aircraft type in those conditions. Jack got behind the aircraft, overshot the turn to final, and failed to recover. This is merely specultion on my part, and in no way is meant to denigrate anyone's opinion or experience with aviation accidents, or to be inflamatory in any way.
I do think that a more rational analysis, and more respectful conversaition, would go a long way towards our collective understanding of what happened, and how that might have occured. Keeping an open mind about what we know, and don't know, would go a long way toward keeping this from spiraling down into a war of words and opinion based on speculation. I appreciate and encourage anyone with an opinion, based on aviation experience or not, to share that opinion with the rest of us.
This is interesting:
