THIS!
This guy has BTDT and had a very similar experience.
Seems like the Army pilot either didn't see the R Jet because he mistook some other lights for the R Jet or he didn't see it out of the night vision goggles field of view.
Stiil, if the helicopter pilot had not climbed out of his airspace altitude limit of 200' ... no harm - no foul. But it only takes a moment to become distracted to pull up a bit.
Also, was the pilot of the hawk in the left or right seat as that gives different perspectives
Reminds me of the two space shuttle disasters
In both cases the danger was forseen by someone at the bottom but that safety info was not acted on because of poor comunication to the top or lack of prioritizing saftey above politics
We may have solved it but wait for the
Why Planes Crash TV investigation show in a couple of years to see if they white wash it
