Halfbaked boy. What a stupid counter argument
People have been killed trying to land, too...
Its all about the degree of risk. To me the risks of trying to swop student pilots on their first ever flight between the front and back of the aeroplane is an avoidable risk. Its a strange enviroment for the student, why spoil the enjoyment of a first flight? Why demonstrate something like this to a student? Or at the very least a potential student, after all it was a trial lesson, hopefully to let the student decide if they were going to continue and learn to fly. Its a bad example of airmanship to the extreme.
