Hi, sorry if I was a bit snippy early on but I think caution need to be applied in thinking this accident was set in motion by just one or two errors.
Someone in another place came up with a nice list of probable contributing factors, I don’t want to C&P that but it went along the lines of:
Very very busy, perhaps excessively busy regional airport (suits politicians travelling to/from their constituencies).
Stupid amount of local helicopter traffic hopping around the city (suits politicians and military).
Result of those two is overloaded airspace with increasing reliance on visual procedures to ensure separation….not great by day, iffy as heck at night.
Lack of adequate ATC staffing (politicians again, cost saving).
ATC staff starting to ignore automated radar generated conflict alerts between traffic because as a consequence of the tight spacing they were happening so often > classic case of what’s known as “normalization of deviance”..they possibly weren’t the only ones guilty of that..we will see.
Nobody at administration and/or political level really taking an interest in any of the above, even when they were flight crew reports of possible/actual conflicts (such as the one you mentioned from the night before the accident) because doing so that might have meant reducing helicopter flights or flights out of DCA…maybe shifting some to out of town to Dulles.. not something the really senior politicians would have welcomed.
So blind eyes were turned and staff at an operational level struggled along doing their best with luck playing a large part in preventing accidents..and finally a couple of nights back the luck ran out.
Sorry for the long post but to conclude it’s possible the actions of Blackhawk crew and/or the controller will probably end up being deemed the main reason for the accident, but they, plus the airliner occupants look to have been victims of a neglected failing system, rather than victim of something deeper.
