Len was a dear friend, squash partner, and former airplane partner. His brother, Greg, was a friend also. Both of them were rock-solid individuals. To correct some speculation on the board, his plane was a turbine Bonanza. He flew it almost every week in conjunction with his dental practice. He took his flying seriously. I knew Len as someone who would land and wait out bad weather. I saw that type of reaction firsthand. I, too, have listened to the atc tapes up until his handoff to Ft. Worth center and looked at the track on flightaware. I do aerial survey work and in reviewing some of my flights, they can look very similiar (screwy looking to someone un-accustomed to knowing what is going on) And yes, sometimes the FA data looks like it has gone into coast mode. I am at a loss to explain what might have happened at this juncture and look forward to seeing the final report to try to make some sense of it all. Mostly, I am just incredibly saddened at the loss of four precious lives.
