Flying through a NOTAM'd display area
Just a quick gauge of opinion.
I'm an ATCO and Safety Manager at a busy military airfield near the east coast.
During a display practice involving a high performance FJ, a PA 28 was observed to fly through the overhead at 4000ft despite a NOTAM warning of the display practice occurring 5nm radius up to 8100ft. To add to the story they weren't speaking to anyone and squawking 7000 without mode C.
What is the point of view from users here about flying in Class G airspace close to busy airfields without speaking to any one of a number of ATC units?
