In the new FLYING (April 2007) Dick Karl mentions his use of flightaware.com on Page 92.
Dick’s column has become my favorite aviation reading. I’m not sure how this happened, but this guy is living my life. He has a non aviation career he seems to love and then he has a great airplane and wonderful flying experiences. To top it off, he gets to share his experiences through his writing.
