Certainly. That doesn't even need an investigation to determine.
In a helicopter, a 360 degree flying machine - if you are flying in an area where airplanes are, priority #1 is elevation parameters of where you are. Nothing else comes before that. Nothing.
So this tells me, incorrect elevation parameters were given.
In the flight path of the helicopter, you can clearly see that the black hawk made a turn that was in a direct path used regularly by commercial airlines. 100s of times a day. No way, now how should that helicopter be there. So either air traffic gave wrong coordinates, or the pilot misheard them and fucked up,
No matter - WTF was a training exercise being done in the exact same area as commercial airport traffic?
