Only 43 years for me. Though, my flying club bought the first Cessna 152 in Canada. It was a rainy gusty day, and my instructor sent me first solo in it. The airplane, with 33 hours total time (of which about half would have been ferry time), had about twice my flying experience during that flight! That plane flies in private ownership to this day, with more than 15,000 hours on it. Amusingly, one of the next 152's to join the club's fleet, also in '77, is still in commercial flight training service with another local school. 'Costs more by the hour now though.....
