Plane collides with Blackhawk helicopter Washington DC

[Zaphod58]

Im just trying to wrap my head around it all, and put the map with the video, another thing isn't ATC supposed to call out heading and altitude? as in "flight xxx maintain adjust whatever the proper course heading and altitude, etc. and aren't you referring to the ATC radar? 

What did the altimeter in the helicopter say?

That’s two of the questions that have to be answered. They’re expecting to read the CSMU from the helicopter today.

The controller was controlling several planes and didn’t call out the UH-60 to the CRJ for some reason, even though he called out the CRJ to the UH-60 several times. The CRJ crew was busy with the last minute runway change, and would have been looking for the runway and ensuring that they were lined up.
