There were several large collections that were destroyed by fires or storms, while in a museum or hangar, San Diego Air musuem ( arson ), Weeks museum (hurricane), a air museum in france (fire), Canadian Warplanes (fire), Bradley Air Museum (tornado), Air Zoo, (drunk driver). Nothing is safe in this world, but you can take steps to reduce the risk, and flying them responsibly is one way to do this. No pilot says I am going to go fly this plane into the ground and kill myself and destroy the plane, no more than you go out and do the same thing in your car. Accidents happen, that is what happens when humans are involved. Again, I point to the 307 as a example, nothing wrong with the plane, other than the gas tank were full of air instead of 100LL, and that was the pilots responsibility. A great many times, a crash was not caused by the plane, but who was flying the plane. Pilots at times = Faulty control stick actuators, or Faulty control wheel input devices.
