Could it be this becomes another case that the regulatory defined airplane exterior (including landing light) lighting (especially for small RJ) is simply insufficient to let it stand out in the airport / city Xmas tree of lighting?

And the chopper crew simply had the next airplane in sequence of landing in sight and not the one they collided with?

RIP

Not sure how an approach like this one can be flown with an ILS, even a GPS based approach I have my doubts to be able to fly that precise, etc.

I think, the better option would be to not rely on "bright lights" but suitably illuminated big surfaces, IE an airplane should illuminate its own surfaces. For this particular case, that might not have made a big difference, given the near head-on approach for a long time.

Can I argue this is the 'fatal runway incursion' everyone has been warning the US is going to have?
This accident was certainly "setup" in the procedures defined in this area, heavily relying on Humans not making (altitude (settings)) mistakes and Humans detection opportunities, for which we all know, the human is not really that well-designed for from scratch.

For this case, the helicopter corridor was designed to be below the approach path, though when the human makes even a small mistake and/or the weather makes the approach path a bit lower, things can go haywire quite easily.

US ATC needs an immediate review because this crash might not be the only one for us in 2025...
I think, it's pretty early to call out this to be an ATC issue. Not to say, the whole issue is just built into the system being used in crowded airspaces, with very limited reserves for human mistakes.

With the CRJ crew probably having their attention focused to aim for runway 33, while performing the circle to approach. With a "clear to land" obtained, they even might be less aware, there might be something out there on a collision course with them.

Not to say, the helicopter declared a "CRJ in sight", which also implies from that moment on, the separation became their responsibility.

When flying myself, I am very hesitating to "accommodate" to ATC's information about other aircraft around me, since I then take over the separation responsibility, even when losing sight of the other aircraft(s).

At the same time the following aircraft on approach to R01, an AA A319 on flight 3130, is above the Woodrow Bridge on finals. Possibly the helicopter crew at some point confused the A319 for the CRJ.

The helicopter crew again confirms they have “the aircraft” in sight and requests visual separation, but surely if they had the CRJ in sight at less than 200’ vertically and half a mile away they would be taking immediate evasive action and not requesting visual separation???
The whole mechanism of "aircraft in sight" no longer works, when the airspace is crowded: "Which aircraft are you supposed to have in sight" ???????

At this point the ATC has NO further responsibility for separation, that is now the SOLE responsibility of the helicopter crew who accepted it. Clearly they did not have the CRJ in sight, what they were looking at will only ever be conjecture. Visual separation at night in such a busy piece of airspace is clearly a ridiculous procedure..... but it is a procedure that can currently be used. The ATC did nothing wrong, the CRJ crew did nothing wrong and more than likely the helicopter crew PROBABLY didn't do anything g wrong on purpose, there was o ly one airaft though out of place, a situation ONLY possible through an outdated and potentially dangerous procedure. My airline doesn't allow visual separation either day or night and only allows visual approaches by day, why be GA in Jets with paying passengers?
Yep, the system in place just does not work once the airspace becomes crowded, "IE which airplane are you supposed to have in sight" ?

With only one other airplane, it's clear, with more than 1, it becomes a gamble.

e. A visual approach is not an IAP and therefore has no missed approach segment. If a go around is necessary for any reason, aircraft operating at controlled airports will be issued an appropriate advisory/clearance/instruction by the tower. At uncontrolled airports, aircraft are expected to remain clear of clouds and complete a landing as soon as possible. If a landing cannot be accomplished, the aircraft is expected to remain clear of clouds and contact ATC as soon as possible for further clearance. Separation from other IFR aircraft will be maintained under these circumstances.
For VFR there is a missed approach procedure: Back into the circuit. Which will be a bit hairy, when the "miss" happens (long) before reaching the runway. Depending on the aircraft type, 2 circuit types may be defined: A small one for slow stuff and a large one for the bigger ones. And as usual with VFR traffic, ATC or self-communication is needed to pick the moment of the next landing attempt.

One can discuss whether this is a procedure or not, though there is at least "something".
