1. The chopper didn't go down because of the radioactive smoke -- it's propeller hit a crane.

2. There was not females protagonist in the events portrayed (it actually makes a disclaimer about this instance of "woke" -- alluding to it being a plot device needed to flesh-out the story).

3. There was not "I WANT THE TROOF / YOU CAINT HANDLE DA TROOF!!" speech decrying the internecine lies and secrecy of the Soviets.

Other than that (from what I recall), it was a good mini-series and certainly worth watching; with enough here to get the gist of it and whet the appetite for the unvarnished version of the event.
