Pete Hegseth's comment: A mistake was made.

31. Simpler explanation: helo pilot saw and avoided the wrong plane in a crowded airspace.

Something like that happened before.

There were two airliners on final approach, one right behind the other.
The CRJ's lights blending into background city lights may also
have been a factor. Other reports say the Army pilots were training
with night vision googles. A mistake was made, an apparently
easy one to make, as there was a near miss there a day earlier.
