I'm not an airspace expert; the CASA/RAAF study recommended a number of changes to the Williamtown airspace, but it forthrightly rejected Class D as a solution. Who's right; CASA/RAAF or Dick Smith? If you think you're right, then you need to do a lot more than jump up and down on the sidelines making noise. You need to show that they are wrong - hyperbole and insults won't make a scrap of difference!
