The plane approaches from the South and banks gently west toward the airport, what seems like a very typical approach for anyone who has flown into National.
The helicopter path is bizarre. Travels SE past Hain's Point, the turns SW toward Alexandria, then adjusts to a course that is due South. Then just before the collision, turns fairly hard SW and straight into path of the plane, which according to ATC was on a steady, normal descent.
Why does the helicopter turn hard toward National right before collision? Why do they turn toward the middle of the river at all? Even if flying higher than normal, if they had just maintained that due South course, they would have missed the plane (still too close for comfort and would require review, but without the tragic deaths of nearly 70 people).
I don't get it.
The path is plotted from I assume early ADSB data. This gives off points that can be off by a few feet here and there. The travel between these points is not a straight line. The path looks weird on the graphic but in reality was a lot smoother than this data. The final NTSB report will include more precise paths.
That said the path definitely looks to be hand flown as 99% of helo operations are (not even sure these have an autopilot on them.)
The crossover of the Potomac is also a typical route. The helos from billing regularly dart across between the final approach course. It’s a dumb as crap plan but it has worked. Clearly altitude was an issue and situational awareness. It was hard watching the radar scope on YouTube where you could see the conflict from what looked like 3-4 miles away. This should have been plenty of time for ATC to provide more separation.
