I know a guy who retired at AA with a little over 27,000. I am sure there people with a lot more than that, but that number sure seems impressive to me. That's spending over 3 years solid in a plane!
BTW, that is a funny way of looking at logbooks. My instructor told me that tell people that he has been flying for seven months. That is because he has a little over 5000hrs. Me, I have spend 12 days in an airplane, HA!
