No, nothing official. I have seen lots of aviators commenting about possible scenarios and things like that, but no official word on what happened.
Army helicopter pilots are trained in Alabama at Fort Novosel (previously named Fort Rucker). That is where they learn to fly and then get specific instruction on the exact helicopter they will fly (Blackhawk, Apache, Chinook). They complete that training there and then get assigned to a base where they continue to fly and "train". I do know that Blackhawks fly with 2 pilots. It can be flown by 1 though so it doesn't require 2 people to keep it in the air. I think each time they are flying in a new place they have to learn the airspace and maybe they fly with someone that has done it before as they are learning. It doesn't mean they are just learning to fly because they were trained in Alabama and they don't go to their first duty station until they pass the flight school. If the unnamed pilot was the pilot flying at the time (we don't know this for sure, just me giving a possible scenario) then no matter who is at fault, that pilot could be the one blamed in the media.
We are an Army family no in aviation, but I know several aviation families. I have no knowledge about who these pilots are or what occurred, but I do know what the training process is like and it's hard and all who graduate do so because they earned it. All flights are considered training flights if they aren't done in Combat or flying official personnel. That can give the impression that someone is new or is learning to fly, but that isn't the case. It's required they do so many flight hours so those flights are considered training. Accidents do happen and usually it is the result of a mechanical issue or human error. The day this crash happened a F35 pilot safely ejected from his plane in Alaska before it crashed. Just yesterday they announced 2 soldiers died at Fort Stewart, GA in a training accident. It happens and thankfully innocent civilians are usually not in harms way when it does.
Edited to add the Fort Stewart accident was a vehicle, not helo/plane.
