& DESTROY_OK
 
  Flag: DESTROY_OK(d)
 
  When set on an object, it allows any player to destroy
  it as long as the object is not locked against them. This is good 
  for things like notes, whereby the recipient can destroy the note 
  after reading it, instead of having to look for you to destroy it.
  The DESTROY_OK flag overrides the SAFE flag, so that you do not need to
  give the /override switch to @destroy to destroy a thing that is both
  DESTROY_OK and SAFE. When it is set on any object or the owner of that
  object, that object is destroyed immediately, without delay.
