With iconic aircraft that are seen by the public as "their" history, the public want "their" history preserved. If a Cessna had hit a Jetstream there wouldnt be calls for all similar aircraft to be grounded. This grew up after the war in the mid sixties in UK. I just remember the 25th anniversary of the Battle of Britain, there were very few Spitfires and Hurricanes flying in private hands, probably more today as at any time since they were retired from service. The public may feel they have some ownership of these planes, but they dont. To me the sight of one of these planes flying, is worth a hundred in a hangar.
