Ok, guys, I must come down unequivocally, firmly, without reservation, on both sides of this issue. The problem is not a lack of concrete per metal flying machine. It’s not even a lack of airspace per se. It’s a matter of density plus a lack of compatibility. When everybody is doing 210 kts in the pattern and 180 kts over the marker, they can be packed in pretty tight. But if one of those dudes needs 70 kts on final, it throws a giant monkey wrench into the works.
I’ve been the guy in the 747 that had to go around (blowing 10,000 pounds of gas out the tailpipe) for the C-172 who wouldn’t (or couldn’t) keep his speed up. And I’ve been the guy in the Cessna who had to hold for an hour waiting for a big enough gap between the heavies. There is no easy answer. In the meantime, maybe it’s best, when you are flying light, to stay out of the big, busy airports. Not because you have no right to be there, but because it’s a lot less hassle for everybody.
And BTW, I knew a nice Delta pilot once. Of course he did quit and took a job with Wal Mart.
