ABSTRACT
If offered a choice between flying a glider accompanied by an experienced pilot and driving a Grand Prix car around a racing track, you would choose to fly the glider; but, if offered a choice between driving the racing car and flying a glider solo, you would choose to drive the car. If you are rational, then, given that you prefer the accompanied glider flight to the car drive and the drive to flying solo, you should choose to fly accompanied in preference to flying solo. To choose to fly solo in preference to flying accompanied would therefore be irrational.
