Don't be that person, the one who oversimplifies an accident into a single issue instead of a chain of events - the circling maneuver, the NVG training, the other plane on approach further out, the discrepancy in altimeter readings between PiC/PM in the Blackhawk, stepped-on comms, the list of things that could easily contribute is already an arm's length long.
Edit: you know what would be great? If the FAA had the resources necessary to implement NTSB's recommendation backlog. Do you feel firing lots of FAA staff helps us or hurts us on that front?
You ask what the army should do. You answer yourself: foster an environment where this behavior is rooted out. Since she didn't feel safe to report, they clearly failed at that duty.
Why? Watch Orville instead.
