This jumped out at me:

(From the link)
"National Transportation Safety Board statistics show that 97 percent of
general aviation accidents and 93 percent of commercial aviation accidents
occur within five miles of airports."

I'm calling it 100 sq miles around each airport:
78.5 sq miles for "r" = 5 miles.
113.04 sq miles for "r" = 6 miles (includes 5,000 ft runway)

In San Diego County, alone, there are 16 airports.
100 sq miles x 16 = 1,600 sq miles
1,600 sq miles = 40 miles x 40 miles (in this one county)

NTSB stat (above) will be true, in that much airspace in SD County.
