That is truly appalling. You have my deepest sympathy. I dread to think how vulnerable most parked or hangared aircraft are to vandalism and arson. I have seen adverse comment about the new security fencing at Sywell, but perhaps we all face that in the future.
I despair at the cause. I live in an area where million quid houses are a few minutes slouch from some wretched estates. The streets are patrolled by the blank faced, hooded top wearing youths of the underclass. They look into the brightly lit houses with their books, paintings and antiques and at the shiny cars parked outside and think only of destroying what they see: they don't appear to have any aspirations even to get things for themselves. Part of me sympathises with their hopeless situation, the other part of me would like them to be force fed to their parents on live television. Arrrgh, it is hateful to turn into a Daily Telegraph columnist.
