This does not comport with a report I heard yesterday. That the small plane pilot was ordered to descend and did not.
I heard they did not descend as well. Hopefully, a link will emerge. If true, these guys are toast.
Let's see, the pilots of the Embraer Legacy 600 were directed to descend in a part of the airspace where radio communications with controllers was stated to be less than optimal. They may have never heard the directive/clearance, and the controllers may have assigned them the wrong FL from a previously assigned clearance...much more than meets the eye here, and it smells a bit like CYA on ATC's part to me at this time...
