ATL93FA061A NTSB FATAL MIDAIR FEB 1993.
DAY/VFR/POSITIVE CONTROL AIRSPACE/EXPERIENCED AVIATORS/EVERY AIRCREW MEMBER WAS AWARE OF ALL THE AIRCRAFT WITHIN AIRPORT TRAFFIC AREA....... PILOT DOES SOMETHING D-D-D. DUMB/DANGEROUS/DIFFERENT THAN EXPECTED.
Very Similar circumstances in this midair I am very familiar with. In "HARD VFR" weather, see-and-avoid by the eyes in the cockpits is the predominant rule governing separation. The person controlling the activity/airspace is only functioning in an "advisory role."
