Once again, quite a bit of time has passed since I wrote my last article. I am now an instructor at a small flight school in California. My students are young and not so young, and include college kids, retired executives, some corporate management types, a painter, and the airfield fuel-truck driver. They are bold, they are timid, they are coordinated, they are uncoordinated, they are organized and they are disorganized. Some are too smart for their own good. One or two don't know how talented they really are, laughing while performing difficult tasks that make others freeze with fear. I teach and I watch and I marvel at the complexity of the interaction: the transfer of knowledge and skills from one person to another in the crammed cockpit of a Cessna 152.
