It is sad to see lovely old aircraft crash and even worse to have a death, but most of the modern pilots flying them are far more skilled than their wartime counterparts ever were. The attrition rate during the war due to "pilot error" was huge, more than enemy action I think,at least in fighter types. You were flying a spitfire or Mustang at about 7o hours clinging on to dear life. This of course speaks volumes for their courage and dedication, but vfr you are not comparing like with like. These aircraft were not meant for low level aeros, nor were they built for a long life, so I agree that they should be looked after.
